China's overall resource structure can be summarized as "rich in coal, poor in oil and little in gas". Coal accounts for more than 90% of the proven energy reserves. China is the world's largest coal producer and consumer, and coal, the main form of energy in China, will not change for a long time in the future.
According to the data released by the China Federation of petroleum and chemical industries, China's oil import fell for the first time in 2021, but its external dependence reached 72%, which is still far higher than the internationally recognized safety warning line of oil external dependence of 50%. At the critical moment of China's rise, the full development and utilization of coal resources is an important means for China to prevent other countries from getting stuck. It is very important for China to adjust the energy structure and reduce energy imports.
According to the report released by CMRC Zhongyan Century Consulting, coal chemical industry can be divided into traditional coal chemical industry and modern coal chemical industry: the output of coke, synthetic ammonia and calcium carbide, the main products of China's traditional coal chemical industry, ranks first in the world, but the added value of the products is not high, the technical content is low, the overall production capacity presents a surplus situation, and the traditional coal chemical industry market will be reduced in the future. Modern coal chemical industry can obtain clean and efficient energy and basic chemical products such as methanol, ethylene glycol and olefin through advanced technology and deep processing of coal, which is an important direction for the development of coal chemical industry in the future.
In coal gasification, coal to olefin and coal to ethylene glycol technologies are relatively mature, with strong downstream market demand and rapid capacity growth; As the core technology of coal to natural gas is not mature, there are few new projects at present. With the increase of downstream market demand and the continuous improvement of technology, the production capacity will gradually increase. Since the implementation of the environmental protection tax law in China, the traditional fixed bed process with high energy consumption and high pollution will be phased out. In contrast, the entrained flow process has lower energy consumption and stronger environmental protection, and is expected to become the mainstream process of coal gasification in the future.
Coal liquefaction technology usually includes direct liquefaction and indirect liquefaction. The direct liquefaction fuel has higher conversion efficiency, better environmental protection performance and more by-products, which can just solve the two major problems of fuel shortage and environmental pollution in China. Therefore, it is of great strategic significance.
Modern coal chemical industry is one of the methods to replace petrochemical industry. In order to deal with the problem of resource security in China, the status of modern coal chemical industry as China's strategic technology reserve will not change in the short term.
