At present, the new crown pneumonia epidemic has a huge impact on the global economic order and economic activities, profound changes in geopolitics, and increasing pressure on energy security. The development of modern coal chemical industry in my country is of great strategic significance.
Recently, Xie Kechang, deputy dean of the Chinese Academy of Engineering and director of the Key Laboratory of Coal Science and Technology of the Ministry of Education of Taiyuan University of Technology, wrote an article that modern coal chemical industry, as an important part of the energy system, must “promote energy production and consumption revolution and build a clean Low-carbon, safe and efficient energy system” is the overall guideline, and the basic requirements of “clean, low-carbon, safe and efficient” are the basic requirements for the development of the modern coal chemical industry during the “14th Five-Year Plan”. The “six guarantees” mission requires that a strong energy system guarantee for the full restoration of production and living order and the recovery of China’s economy.
The strategic positioning of my country’s coal chemical industry has not been clear
Xie Kechang introduced that after years of development, my country’s modern coal chemical industry has made great progress. First, the overall scale is in the forefront of the world, second, the operation level of demonstration or production facilities has been continuously improved, and third, a considerable part of the technology is at the international advanced or leading level. However, there are still some restrictive factors in the development of modern coal chemical industry in my country.
The strategic positioning of industrial development is not clear. Coal is the main force of China’s energy self-sufficiency. The society lacks awareness of modern coal chemical industry and green high-end chemical industry that can be clean and efficient, and partly replace petrochemical industry, and then “de-coalization” and “smelling chemical discoloration” appear, which makes China’s coal chemical industry strategically positioned It has not been clear and clear, which has led to policy changes and the feeling that enterprises are riding a “roller coaster”.
Intrinsic deficiencies affect the level of industrial competitiveness. Coal chemical industry itself has low energy utilization and resource conversion efficiency, and environmental protection problems caused by the “three wastes”, especially coal chemical wastewater, are prominent; due to the indispensable hydrogen adjustment (conversion) reaction in modern coal chemical technology, water consumption and carbon emissions are high ; Due to the large number of primary products, the inadequate development of refined, differentiated, and specialized downstream products, the comparative advantage of the industry is not obvious, and the competitiveness is not strong; due to the gap in technology integration and production management, product costs are high, and overall efficiency remains to be Improve etc.
The external environment restricts industrial development. Petroleum price and supply, product capacity and market, resource allocation and taxation, credit financing and return, environmental capacity and water use, greenhouse gas and emission reduction are all external factors that affect the development of my country’s coal chemical industry. The single or superimposed factors in certain periods and certain regions not only severely restricted the healthy development of coal chemical industry, but also greatly reduced the economic anti-risk ability of the formed industries.
Should improve economic efficiency and anti-risk ability
Energy security is an overall and strategic issue related to China’s economic and social development. Faced with the complex domestic and international development environment, China’s clean energy development requires active development of high-efficiency pollutant removal technologies, multi-pollutant coordinated control technologies, and wastewater treatment. Zero-emission technology and “three wastes” resource utilization technology, relying on demonstration projects to achieve industrialization as soon as possible, and at the same time, based on the atmospheric environment, water environment and soil environment capacity, scientifically deploy the coal-based energy chemical industry. On the other hand, it is necessary to establish and improve coal-based energy and chemical clean production standards and related environmental protection policies, improve the clean production management system of project approval, full-process supervision and post-evaluation, clarify supervision responsibilities, form an accountability system, and guide and regulate coal-based energy Clean development of the chemical industry.
Xie Kechang suggested that in terms of low-carbon development, it is necessary to clarify what coal-based energy chemical industry can and does not do in carbon reduction. On the one hand, it is necessary to make full use of the advantages of high-concentration CO by-product in the process of coal-based energy chemical industry and actively explore CCUS technology. Advanced deployment of high-efficiency CCS and cutting-edge research and development of CCUS technologies such as CO flooding and CO-to-olefins to expand the utilization of CO resources; on the other hand, it is not possible to “throw in the mouse” and ignore the process attributes of the coal-based energy chemical high-carbon industry, and inhibit The scientific development of coal-based energy chemical industry requires disruptive technologies to break through the bottleneck of emission reduction at the source and energy saving and efficiency improvement, and weaken the high carbon nature of coal-based energy chemical industry.
In terms of safe development, the government should clarify the strategic significance and industrial positioning of coal-based energy chemicals as the “ballast stone” for my country’s energy security, and earnestly take the clean and efficient development and utilization of coal as the foothold and primary task of energy transformation and development. At the same time, it is necessary to lead the formulation of coal-based energy and chemical development planning policies, guide disruptive technological innovation, and orderly promote coal-based energy and chemical industries to gradually achieve upgrading demonstration, moderate commercialization and full industrialization; formulate relevant guarantee economic and financial policies to improve Implement the economy and competitiveness of enterprises, form a certain scale of oil and gas energy substitution capabilities, and create a good external environment for the development of modern coal chemical industry.
In terms of high-efficiency development, it is necessary to actively carry out the research and industrial application of high-efficiency coal-based energy chemical technology such as direct synthesis of olefins/aromatics, coal pyrolysis and gasification integration, and realize breakthroughs in energy saving and consumption reduction; vigorously promote coal-based energy chemical industry and The integrated development of power and other industries, extending the industrial chain, producing high-end, characteristic, and high-value chemicals, and improving economic efficiency, risk resistance and competitiveness; deepening the management of energy-saving potential, focusing on promoting a series of energy-saving technologies such as low-level thermal energy utilization technologies , Coal-saving and water-saving technologies, optimize process technology, and improve energy resource utilization efficiency.
