Modern coal chemical industry innovation development layout plan

Modern coal chemical industry refers to the industry that uses coal as raw material and adopts advanced technology and processing means to produce alternative petrochemical products and clean fuels. In order to promote the innovation and development of the modern coal chemical industry, expand the sources of petrochemical raw materials, form an industrial pattern that is complementary to and coordinated with the traditional petrochemical industry, and implement the work deployment of the "Petrochemical Industry Planning and Layout Plan" and the "Guiding Opinions on Structural Adjustment of the Petrochemical Industry to Promote Transformation and Increase Efficiency", the modern coal chemical industry innovation and development layout plan is proposed.

First, the necessity of developing the innovative development layout of modern coal chemical industry

Petrochemical products are important basic raw materials for the development of national economy, with huge market demand, but constrained by oil and gas resources, the degree of external dependence is high. In 2015, the external dependence of crude oil, natural gas, ethylene, aromatics and ethylene glycol reached 60.8%, 31.5%, 50.4%, 55.9% and 66.9%, respectively. China is relatively rich in coal resources, and the appropriate development of modern coal chemical industry with innovative technology plays an important role in ensuring the safety of petrochemical industry and promoting the diversification of petrochemical raw materials.

After years of efforts, China's modern coal chemical technology has made a comprehensive breakthrough, the level of key technologies has been in the world's leading position, coal to oil, coal to natural gas, coal to olefin, coal to ethylene glycol basically realized industrialization, coal to aromatics industrial tests have made progress, and successfully built a bridge from coal to petrochemical products transformation. However, at present, the industry as a whole is still in the upgrading demonstration stage, not yet fully equipped with the conditions of large-scale industrialization, system integration level and pollution control technology to be improved, production stability and economy to be verified, industry standards and market system to be improved, and there is no ecological environmental capacity and water resources carrying capacity, blind planning and construction of modern coal chemical projects momentum. In view of the existing problems, it is urgent to strengthen scientific planning, do a good job in industrial layout, improve quality and efficiency, resolve the contradiction between resources and the environment, achieve clean transformation of coal, cultivate new economic growth points, further improve the maturity of application demonstration, reliability of technology and equipment, and gradually build a modern coal chemical industry system with perfect industry standards, complete technical routes and complete product categories. We will promote safe, green and innovative industrial development.
