Coal chemical industry is an industry that takes coal as raw material and generates chemical and energy products through chemical reaction. It is a deep processing industry of coal.
In recent years, the development of coal chemical industry in China has gradually heated up, showing a disorderly and overheated trend. Various coal producing provinces (regions) have thrown out huge coal chemical industry development plans. Not only the capacity of traditional coal chemical products represented by synthetic ammonia, methanol and PVC has expanded sharply, but the products under construction and planning are mainly positioned in coal to oil, methanol / dimethyl ether and methanol to olefins. All kinds of enterprises and funds have entered the coal chemical industry, including coal enterprises, electric power enterprises, chemical enterprises, state-owned funds, private funds, domestic funds, international funds, etc. The investment is huge, the scale is large, and the selling speed is amazing. The real concern is not just the scale, but the emerging construction * *.
The state has several policies and regulations on the development of coal chemical industry. In recent years, some situations in the development of coal chemical industry deserve attention: Coal chemical industry is an industry with obvious economies of scale. Most of the coal chemical projects under construction or planning can not reach the scale stipulated by the state. Some enterprises are often restricted by capital, technology and other conditions, and adopt the way of expanding the planning and implementing it by stages. This is not only conducive to the smooth passing of the review, but also occupy more resources, but it does not reflect the economies of scale. Coal chemical industry is a high water consumption industry. Development should measure water, and strictly control the construction of coal gasification or coal liquefaction projects in water deficient areas on the premise of not competing with agriculture, people and ecology for water. However, in order to develop the economy, some coal producing provinces and regions take resources as a means and ignore the carrying capacity of ecology and environment, attract investment on a large scale, and even introduce multiple large-scale coal chemical projects with the same structure in the same area and the same development zone; Many large-scale coal chemical projects have been arranged in many areas with serious water shortage. Relevant water conservancy departments have warned，The construction of heavy chemical industry in the middle of the Yellow River that exceeds the carrying capacity of water resources is likely to trigger a "water war" among industry, agriculture and ecology, and pose a serious threat to the water intake of provinces in the lower reaches of the Yellow River. In the name of building coal chemical projects, many regions seize and seize resources, seize a large number of coal resources, and unilaterally pursue the rapid development of the industry at the expense of resources. The coal chemical industry in many areas has just started, and the coal resources have been divided up. Many large foreign companies are in contact with relevant parties and directly participate in large coal chemical projects. China's catalogue of industries for foreign investment(2007 Revised in)>regulations:The production of large-scale coal chemical products is controlled by China. According to the data, at present, foreign investment has accounted for a considerable part of China's planned investment in coal chemical industry during the Eleventh Five Year Plan period. Various disguised projects controlled by foreign investors and relatively controlled by foreign investors have emerged one after another. China's coal chemical industry fever has brought a new era**The disorderly repeated introduction of coal gasification technology. A dry coal gasification technology is only used for circulating power generation in foreign countries, but not used in chemical production. However, some domestic enterprises have rushed to introduce regardless of risks, and have introduced more than 20 sets by the end of 2007. as report goes，Up to now, none of the several devices running with this technology can realize long-term stable operation. Almost all coal gasification technologies in the world(Some technologies are not mature)It has been introduced in China. China has become the first test of coal gasification technology applied in chemical industry in many foreign countries(Or enlarge or improve or demonstrate to make it applicable and mature)The base bears a huge price of pay and risk. The prominent manifestation of overheating in China's coal chemical industry is "every coal must be changed". In order to transform resource advantages into economic advantages, almost all coal producing areas and even coal transfer areas should vigorously develop coal chemical industry(Nearly 20 provinces and districts across the country plan to "build" coal chemical industry into a pillar industry)，Hope in coal chemical industry GDP. So far, how many coal chemical bases and coal chemical projects are under construction or planning in China? What is the total investment? What is the balance between production and demand of products? Are the conditions required for the development of coal chemical industry matched? I'm afraid few people can make it clear. In order to make overall planning, rational layout, scientifically guide and standardize the development of coal chemical industry, and effectively correct some places' blind planning and competing construction of coal chemical projects regardless of the carrying capacity of resources, ecology and environment, which may have a potential negative impact on the sustainable, healthy and steady development of economy and society, The national development and Reform Commission issued the notice on strengthening the construction management of coal chemical projects and promoting the healthy development of the industry on July 7, 2006. Subsequently, a series of relevant policies and regulations were issued one after another to curb the disorderly development of coal chemical industry to a certain extent, but it is far from reaching the expected goal. For various reasons, the disorderly and overheated development trend has not been completely curbed. The super strong and ultra-high speed development of the above coal chemical industry has aroused the deep thinking of people in the industry. Is this situation in line with the scientific outlook on development? Are you happy or worried about the sustainable development of the national economy and energy security? There are conditions for the development of coal chemical industry. Coal can be "melted" whenever there is money, but it is not "melted" when there is money. At present, the hot spot in the development of coal chemical industry is energy chemical products. This paper tries to think and discuss relevant problems, and put it bluntly for reference.
Coal based energy
Thoughts on chemical products
Coal to oil
High oil price hastens China's coal to oil industry
All localities have high enthusiasm for the development of coal to oil. All provinces with coal resources have carried out preliminary research, planning and fund-raising construction of large-scale coal to oil projects. According to incomplete statistics, by the end of 2006, 15 coal to oil projects had been planned in China. Among many coal to oil projects, except Shenhua, 3.2 million tons/Annual output of Yankuang 1 million tons/160000 tons per year in Lu'an/Except for the three projects approved by the national development and Reform Commission in, the other projects belong to local or enterprise planning. be under construction(132 10000 tons/year)And the total scale of the planned coal to oil project has reached 40.17 million tons/Year.
Pay full attention to the risk of developing coal to oil
The biggest power of coal to oil is that coal reserves are relatively more than oil and gas resources. Secondly, according to the existing oil price, coal to oil may be profitable. However, coal to oil is a huge systematic project, involving coal resources, water resources, ecology, environment, technology, capital and many social supporting requirements, and the requirements of conditions are high. We should attach great importance to the risk of coal to oil industry. -In terms of technology, there is no industrial device in operation in China that can learn from direct coal to oil technology, and there is no industrial device in foreign countries. Shenhua's direct liquefaction coal to oil industrial plant is the first to be built in the world, and there are many engineering risks from engineering amplification, equipment manufacturing, catalyst performance, production process control and so on. Although Sasol has mature indirect technology, the transfer fee is too high. Yankuang and Lu'an's indirect method technology is in the industrial demonstration stage. China's coal to oil technology has not reached the stage of large-scale industrial promotion. -In terms of investment, 10000 tons will be built/The annual coal to oil plant requires an investment of 100 million yuan to build a set of coal to oil plant with a capacity of more than one million tons, often with an investment of tens of billion yuan. The input-output ratio is too low, resulting in high equipment depreciation expense and bank loan interest rate amortized in product cost accounting. The cost of coal to oil remains high. -In terms of cost, compared with the oil price and coal price at the time of project establishment, the construction of large-scale coal to oil project is expected to obtain huge economic benefits. However, with the rise of oil price, the price of coal will rise accordingly. With the introduction of the new policy of national resource fee and environmental protection fee, the tax increases and the coal price increases accordingly. Every 100 yuan rise in the price of coal/Tons, the cost of coal to oil will increase by 5～8 dollar/Tons. Up to now, the coal price has increased many times than that at the time of evaluation, and the coal price will continue to rise in the future. In addition, when the unit is completed and put into operation, the cost and labor cost of public works such as water, electricity, steam and transportation also far exceed the cost at the time of evaluation. The cost of coal to oil will also face the market risk of international oil price fluctuations.
Start the initial stage of coal to liquid project
The distribution of points at different stages should be strictly controlled
Based on the national conditions, it is necessary for the state to include coal to oil in the strategic reserve project of energy security from the perspective of energy security strategy. In order to avoid risks, in the initial stage of starting the coal to oil project, the state should concentrate financial resources to build a set of industrial demonstration devices with different device sizes, different process routes and different technical sources. After the device is completed, experts will comprehensively evaluate these demonstration devices, select the coal to oil process with the best technical and economic indicators, and promote it appropriately at the right time. At present, China's coal to oil industry is in the stage of industrial test and demonstration. Before the first set of technology fails to pass the review, it is not suitable to start the construction of similar new projects.
China should master the core technology of coal to oil
When deploying coal to oil projects, we should make an overall plan to introduce technology and adopt domestic technology. We will intensify efforts to support domestic new technologies with independent innovation. Shenhua's direct coal to oil technology and the indirect technology developed by Shanxi Institute of coal chemistry, Chinese Academy of sciences have made significant progress. We should organize forces to promote the process of domestic technology demonstration and test, and strive to master the core technology of coal to oil as soon as possible.
Size up the situation, weigh the pros and cons and develop moderately
With the advent of the era of high oil prices, developed countries attach great importance to the research and development of coal to oil technology. Although the United States, Europe, Japan and other countries and regions have mastered the core technology of coal to oil, they lack industrial demonstration devices and fail to reach the stage of industrial application. as report goes，So far, there is no coal to oil project in the United States. Because the investment is too large, and the technical risk and market risk are also great, the enterprise is still waiting and watching. In addition, the important factor hindering the development of coal to oil is environmental pollution. A large amount of wastewater, waste gas and waste residue are produced in the production process, which is seriously polluted. At present, we should concentrate on industrial technology development. Industrial demonstration devices should strive to be advanced and reliable, do a good job in technical reserves, and comprehensively and deeply study the development of coal to oil. We should take a holistic view of the situation at home and abroad, size up the situation, weigh the pros and cons and make prudent decisions. In the strategic arrangement of alternative energy, China should not focus on the only non renewable resources, but should focus on renewable clean energy.
Methanol / dimethyl ether
The supply and demand pattern of methanol in the international market has changed. Whether the price of coal to methanol can compete with the import price of natural gas to methanol deserves attention
Natural gas is the main raw material for methanol production all over the world. In 2006, the world's total methanol production capacity was 46.95 million tons/Year. two thousand and seven～2010 The annual growth rate of global methanol production capacity in was 4.5%～5.0%，By 2010, the production capacity will reach 58 million～6000 10000 tons/Year. Since the beginning of this century, new units have been concentrated in areas rich in natural gas resources such as the Middle East, Latin America and East Asia, seeking to occupy the market with cost advantage. The scale of the device is also large(5000～12000 ton/day)Trends. The change of world methanol production pattern has led to significant changes in consumption pattern. Methanol consumption in developed countries and regions such as the United States, Europe and Japan has gradually changed from self-sufficiency to import. China has also become the target market for methanol producers in the world.
In today's global economic integration, international trade competition has entered the Chinese market. When developing methanol industry in China, we should consider two resources and two markets as a whole. Whether China's coal to methanol can compete with the import price of natural gas to methanol deserves attention, especially in the southeast coastal areas. At the same time, we should also pay close attention to the transportation problems caused by the regional imbalance that the main origin of methanol is in the West and the main market is in the East.
Domestic methanol is developing rapidly and disorderly
China's methanol production takes coal as the main raw material, with unreasonable industrial structure, small plant scale, too many enterprises, and various raw material routes and process technologies. Due to the high expectation of the demand for alcohol ether fuel, the development of methanol in China is overheated and almost "blooms everywhere". reportedly，2000～2007 The annual average growth rate of methanol production capacity in China was 24.8%，2007 In, there were 177 methanol production enterprises in China, with a total scale of more than 16 million tons/Year. At present, there are 34 methanol projects under construction and planned to be built, and the total capacity will reach 26 million tons by 2010～3060 10000 tons/Year. China's planned methanol production capacity has exceeded the total production capacity of other countries in the world in the same period.
Methanol exports surged in the second half of 2007. Coal based methanol is a resource consuming product and a low value-added product. It is inappropriate to rely on a large number of exports to digest excess capacity.
Measures should be taken to curb the excessive growth of methanol production capacity, and some projects should be delayed. At the same time, we should accelerate the elimination of a number of backward enterprises with high energy consumption, heavy pollution and small scale. Strive to implement the policy of "closing the small and building the large" to balance the total amount. The scale benefit of methanol plant is very obvious, so we should promote the large-scale of methanol plant.
With the introduction of standards,
Dimethyl ether has entered a period of rapid development
The industrial standard of dimethyl ether for urban gas has been approved, and the national standard of dimethyl ether mixture for urban gas is expected to be promulgated in 2008. With the introduction of the standard, dimethyl ether is ushering in a new round of construction boom. At present, the effective production capacity of dimethyl ether in China has exceeded 1.2 million tons / year. There were 13 new dimethyl ether projects in 2007, with a total production capacity of nearly 7 million tons / year. It is estimated that the consumption of dimethyl ether will reach about 2.2 million tons in 2008; In 2010, the total production capacity will reach 10 million tons / year.
Possible risks faced by the rapid development of alcohol ether fuel
It is reported that the low proportion methanol fuel standard has been submitted for approval, and the draft of high proportion methanol fuel standard will be completed in the first quarter of 2008. Shanxi and other provinces and cities have accumulated experience in trying methanol gasoline for many years, but whether methanol toxicity, environmental impact and engine damage can be avoided in the process of large-scale promotion of methanol gasoline needs to be tested by practice .
The production of dimethyl ether faces the market risk of high cost and low price of imported methanol. Based on the current methanol market price of 3000 yuan / ton, the production cost of dimethyl ether is more than 5000 yuan / ton. The calorific value ratio of LPG to dimethyl ether is 1:1.6, that is, 1.6 tons of dimethyl ether is equivalent to 1 ton of LPG. At present, the CIF price of LPG is about 7000 yuan / ton. Regardless of storage and transportation costs, the production cost of dimethyl ether can be accepted by the market only if it is less than 4400 yuan / ton. In addition, the main production base of dimethyl ether is in the northwest, while the consumer market is in the southeast. Once methanol from the Middle East hits the Chinese market, the southeast coastal areas will use low-cost imported methanol to produce dimethyl ether, which will pose a threat to the production of dimethyl ether in the northwest.
Methanol to olefin
The production technology of producing methanol from coal or natural gas and then producing ethylene, propylene and other low-carbon olefins from methanol is referred to as MTP/MTO for short. The implementation of coal based methanol to olefin project can effectively alleviate the shortage of naphtha in China and the dependence of low-carbon olefins on the international market.
Dalian Institute of Chemical Physics, Chinese Academy of Sciences has mastered the core technology of methanol to olefin (MTO), and the proportion of ethylene and propylene can be adjusted according to the needs of the market. This new technology with independent intellectual property rights has completed the on-site pilot test, and is now building an industrial demonstration device as approved by the state. We look forward to the success of this project. At present, it is not suitable to set up new sites for demonstration tests. At present, all localities are optimistic about methanol to olefin and rush to the top. It is suggested to make a sound decision after the successful operation of the first industrial demonstration unit and passing the appraisal. At present, China does not have the technical conditions for large-scale industrialization promotion.
There are several methanol to olefin projects planned in China, with a total scale of 7 million tons / year. Among them, three projects started construction in 2007, with a total capacity of 1.13 million tons / year. According to the data, the price of methanol is the key to technology and economy. According to the scale of MTO project, the total cost of methanol accounts for 70% ~ 85% of the total manufacturing cost of MTO. In order to reduce the cost of methanol, the methanol plant should be large-scale (more than 1 million tons / year). With the rise of coal price, the cost of coal based methanol increases accordingly. Whether the cost of coal based olefins is competitive with that of petroleum based olefins deserves high attention. In addition, the coal to hydrocarbon ratio of methanol to olefin is 6.1:1 . Whether it is cost-effective to exchange more than 6 tons of coal for 1 ton of low-carbon olefin requires a comprehensive assessment of coal price, resource consumption and impact on environment and ecology. At the same time, the long-term trend of oil price, coal price and methanol price should be analyzed and predicted prospectively.
On the energy utilization rate of coal based energy chemicals
Coal to oil
According to the data , the direct coal to oil process is adopted, and the coal hydrocarbon conversion coefficient (including the total energy consumption of raw materials, fuels and power) is 5:1, that is, 5 tons of coal for 1 ton of oil. According to the heat equivalent conversion formula provided by the National Bureau of standards of the United States, the heat equivalent ratio of oil and standard coal is 1 ∶ 1.4286. Based on this, the heat energy conversion rate of coal is 28.6%, that is, 71.4% of the heat energy is consumed in the process of coal to oil. Using the indirect coal to oil process, the coal hydrocarbon conversion coefficient is 5.3 ∶ 1, and the thermal energy conversion rate of coal is only 26.9%.
Coal to methanol
According to the data , the calorific value of methanol is 22.7GJ(0.776 tons of standard coal), the average comprehensive energy consumption of large coal to methanol unit is 1.54 tons of standard coal, and the thermal energy conversion rate is 50.4%; The average comprehensive energy consumption of combined alcohol is as high as 2.73 tons of standard coal, and the thermal energy conversion rate is only 28.4%.
Coal to syngas / syngas
According to the data , taking the two-stage dry powder pressurized gasification technology of Xi'an Thermal Power Research Institute as an example, 82.5% of the heat energy of the coal into the furnace is converted into syngas. With the different types and processes of gasifiers, the energy utilization rate of coal is also different.
Converting coal gas into methane (synthetic natural gas) is a mature technology. According to the data , one ton of coal can be converted into 400m3 synthetic natural gas. According to the heat equivalent conversion formula given by the National Bureau of standards: 1m3 natural gas = 1.33kg standard coal, the energy conversion rate of coal to synthetic natural gas is 53%. It is reported that recently, relevant state departments have approved an enterprise to carry out the preliminary work of coal to natural gas demonstration project .
The energy conversion rate of coal based liquid energy chemicals is low
The ways of converting coal into energy products in China include coal to oil, coal to methanol / dimethyl ether, coal power generation, coal to syngas / synthetic natural gas, etc. The effective utilization rate of thermal energy of coal with different utilization modes is as follows: coal to oil (26.9% ~ 28.6%) < coal to methanol (28.4% ~ 50.4%) < coal to power generation (40% ~ 45%) < coal to syngas (53%) < coal to syngas (82.5%).
Through the ranking of the effective utilization rate of coal heat energy, it can be seen that the energy utilization rate of liquid fuels such as coal to oil or methanol is low. The target products of large-scale coal chemical projects being vigorously built all over the country are mostly coal to liquid and methanol with low energy utilization rate of coal. In the process of converting coal into renewable energy, China's total consumption of coal is not increased, but it is only in the process of converting coal into renewable energy.
China's energy structure with coal as the main body and extensive utilization has formed unbearable pressure on resources and environment. China's SO2 emissions and CO2 emissions have ranked first and second in the world respectively, of which 80% of SO2 comes from the use of coal, which is an important reason for China's dilemma in atmospheric environmental governance. Now, if we still increase the output of coal to ensure energy demand, it will be constrained by resources, environment, transportation and other aspects, which will be unsustainable.
The development of coal based energy and chemical industry at a super high speed not only does not reduce the proportion of coal in national energy, but also accelerates the depletion of China's coal resources, but also brings environmental pollution problems. Considering China's relatively rich coal resources, perhaps this determines that coal to oil and other energy alternative chemicals can only be moderately developed under controllable conditions.
Utilization of coal to syngas / natural gas
Coal to oil, methanol / dimethyl ether and coal to synthetic natural gas can be used as engine fuel. Coal to syngas has high energy efficiency. In coal producing areas, for example, after coal is made into syngas, it is input into the natural gas pipe network nearby, and the mixed gas of natural gas and syngas is transmitted to end users through the natural gas pipe network, which is one of the optional ways for efficient and clean utilization of coal resources. In theory, the mixture of natural gas and synthetic gas can also drive cars.
Thoughts and suggestions
The development of coal chemical industry is not only related to the development path of China's chemical industry, but also related to national energy security. Starting from the overall interests of the country, standing at the height of the overall situation, we should examine the development trend of the world chemical industry and the reality of our country from a strategic perspective, and think calmly and objectively about major issues such as how to develop coal chemical industry and what kind of coal chemical industry to develop in our country. Under the guidance of China's coal chemical industry development strategy, we must explore the road of sustainable development according to China's national conditions.
The development of coal based energy chemicals requires sound decision-making
From the perspective of world development prospects, future development must rely on renewable resources, but in the medium and short term (such as before 2025 ~ 2030), it is still inseparable from fossil resources (mainly oil, gas and coal). In fossil resources, coal has a large storage capacity and convenient mining and utilization, which is bound to receive extensive attention. In recent years, oil and gas prices have risen. Developed countries (mainly the United States, Europe and Japan) and regions have invested heavily in the utilization of coal and achieved many results. However, the general trend is to achieve the clean utilization of coal through clean coal technology and improve the utilization rate of coal. The key technology is gasification, and the premise is large-scale. The utilization direction of coal is power generation, and there is no plan to develop coal based energy chemicals . Although there are reports of continuous progress in technologies such as methanol to olefin and coal to oil, there is no industrial demonstration unit abroad so far, and mature industrial development experience has not been provided.
Coal, oil and natural gas are fossil fuels. Replacing oil and gas with coal is to replace another non renewable resource with one non renewable resource. The energy substitution strategy must be comprehensively considered. Whether the development of coal based energy chemicals is feasible depends on whether the energy utilization is reasonable, the environment is controlled and treated, and there are certain economic benefits. These three must be combined, that is, adopt the technical and economic route of high energy efficiency, low pollution and economic feasibility. Once the policy orientation and implementation of China's oil alternative energy development strategy are biased, it will lead to excessive consumption and waste of coal resources, although it may slightly alleviate the import pressure of China's oil and natural gas in the short term.
There are many problems in the development of coal based chemical energy products, which depend on our active exploration and in-depth research, and some problems can be concluded only after experiment or demonstration practice. Therefore, we must not underestimate the problems in progress. We need to size up the situation, weigh the pros and cons, make overall plans, make stable decisions, and achieve orderly, appropriate and scientific development.
Change the development mode and develop modern coal chemical industry
The traditional coal chemical industry is a high energy consumption, high emission, high pollution and low benefit industry dominated by low technical content and low value-added products, that is, the "three high and one low" industry. This unsustainable development mode of excessive consumption of resources, serious environmental pollution and extensive can not be sustained. Therefore, it is necessary to timely accelerate the transformation of the development mode of coal chemical industry and strive to promote the development of modern coal chemical industry.
Coal is an inefficient and highly polluting energy. To convert this kind of unclean energy into clean chemical raw materials requires many links, high energy consumption, enlarged emission and heavy pollution. Taking coal to ammonia (using advanced coal chemical technology) as an example, the CO2 discharged is five times that of natural gas to ammonia. Low resource utilization and high consumption will inevitably lead to high emissions and high pollution. The main way to solve these problems is to strive to adopt new technologies.
Modern coal chemical industry is based on new technology. The main difference between modern coal chemical industry and traditional coal chemical industry lies in the integrated application of clean coal technology, advanced coal conversion technology and new technologies such as energy conservation, consumption reduction, emission reduction and pollution control, so as to develop competitive products. Adopting new technology with the times is the core of modern coal chemical industry.
Modern coal chemical industry is a technology intensive and investment intensive industry. The construction and operation mode that is most conducive to resource utilization, reducing pollution, protecting ecology and improving benefits should be adopted to realize sustainable development. Therefore, we should adhere to the integration, base, large-scale and modernization of mineralization and implement intensive management. The development of modern coal chemical industry is quite difficult, which must be undertaken by large enterprises with good quality and strong strength.
Modern coal chemical industry is a resource-saving and environment-friendly industry. Under the new situation, whether sustainable development can be achieved depends on the availability of energy conservation, consumption reduction, emission reduction, pollution control and economic benefits. The development of coal chemical industry must not be at the cost of wasting resources, sacrificing the environment and destroying the ecology.
Focus on energy conservation, emission reduction and pollution reduction, actively adopt new technologies and accelerate structural adjustment
The industrial structure of China's chemical industry with coal-based products as the main body is the main reason for the high investment intensity of chemical industry, large resource consumption, large emission of three wastes, large negative impact on ecology and environment, low effective utilization rate of coal energy, serious waste of resources and large emission of carbon dioxide. The development of China's coal chemical industry should resolutely bid farewell to the extensive development model.
Accelerate the formulation and implementation of China's coal chemical industry structure adjustment plan with technology upgrading as the main content. Relevant enterprises shall meet the targets of energy conservation, emission reduction and pollution reduction within a time limit; We will accelerate the closure and elimination of backward enterprises with large consumption, heavy pollution, small scale and hopeless transformation and upgrading. We should raise the threshold of market access and promote the large-scale of devices. Strive to improve the added value of coal chemical products.
Strengthen macro-control and curb the blind overheating development of coal chemical industry
National coal industry policy(2007 November)It is stipulated that "coal chemical industry should be moderately developed in areas with sufficient water resources and rich coal resources, coal chemical industry should be limited to coal transfer areas and areas with insufficient water resources, and coal chemical industry should be prohibited in areas with insufficient environmental capacity. The State implements protective development of special and scarce coal and restricts the development of high sulfur and high ash coal." The state divides the development of coal chemical industry into "moderate", "restricted" and "prohibited". Even if the region is rich in coal resources, it needs "sufficient water resources" to "moderate" development. However, in our development evaluation, we often use heavy coal resources and light water resources; Not "moderate" development, but "every coal must be changed". We should try to prevent the project consultation and evaluation from being superficial, formalized and formalized. In order to implement the sustainable development strategy, we should do a good job in environmental assessment and energy assessment. It is suggested to suspend the approval and start new projects, and organize review of the approved projects. Strictly implement various policies and regulations to curb the disorderly and overheated development momentum of the coal chemical industry as soon as possible. Efforts should be made to correct various violations in attracting investment. Enterprises should earnestly implement the national macro-control policies and measures, actively support the national macro-control, optimize the investment structure of coal chemical industry, and become a healthy force of the market.
Speed up the revision, improvement and promulgation of the medium and long-term development plan of coal chemical industry
The plan should thoroughly implement the scientific outlook on development, considering both the positive impact of coal chemical industry on national economic development and the possible negative impact. The scale of China's coal chemical industry should adapt to the development of national economy, and the industrial development direction should be consistent with the basic national policy of saving resources and protecting the environment. In the quantification of development objectives, we should take into account the protection and efficient utilization of coal resources, and control the development scale within an appropriate range. In recent years, relevant departments have successively issued a number of policies, regulations, methods and instructions on coal chemical industry. To standardize the development of coal chemical industry in China by planning, and as the main means of macro-control, make China's coal chemical industry embark on the road of orderly, moderate and scientific development.
Adhere to technology development first and strengthen independent innovation
China's coal chemical technology development and independent innovation is not enough. It pays more attention to introduction than development and innovation, forming dependence on foreign technology to a considerable extent, and the key technology is controlled by others. We should carefully formulate and implement the scientific and Technological Development and innovation plan of coal chemical industry, gradually break through various core technologies and realize the localization of major equipment of coal chemical industry. Of course, the development of new coal chemical technology is quite difficult. It is by no means a short-term act of "lifting a hand". It needs high-intensity, unremitting and lasting investment. The development of new coal chemical technology is the core of China's initiative in the development of modern coal chemical industry, and it is a national strategic behavior. Enterprises, especially large enterprises, should really become the main body of technology development and adhere to the close combination of production, learning and research. We should earnestly study foreign advanced technology and do a good job in digestion, absorption and re innovation. Foreign patented technologies that are not applied to similar devices should be carefully evaluated to avoid risks. Introduce mature, reliable, advanced and applicable new technologies with successful and practical performance verified by demonstration. The development of modern coal chemical industry is conducive to the implementation of China's petroleum alternative energy strategy, the structural adjustment of China's chemical industry and the needs of national economic development. The rapid growth of energy demand has brought China into a new stage of developing modern coal chemical industry. Earnestly implementing the scientific outlook on development is the vitality of the development of coal chemical industry. The urgent task is to combine reality, seriously sum up experience and lessons, and accelerate the transformation of the development mode of coal chemical industry.
