The coal chemical industry has become an important part of China's energy structure. Large-scale and large-scale coal chemical projects are emerging. Coal-to-liquids, coal-to-olefins, dimethyl ether to coal, methane to coal, ethylene glycol to coal, etc. At the same time, all relevant scientific research units have been exploring new ways for the efficient and clean conversion of coal and the diversified development of petrochemical raw materials. Therefore, the coal energy and chemical industry will play a leading brand in China's coal chemical industry for the sustainable use of energy in China, and achieved considerable achievements and good performance in the localization of key equipment for coal chemical industry pumps.
