Brief introduction of coal chemical industry

Coal chemical industry takes coal as raw material, which is converted into gas, liquid and solid products or semi-finished products through chemical processing, and then further processed into chemical and energy products.

Mainly includes coal gasification, liquefaction and dry distillation, as well as tar processing and calcium carbide acetylene chemical industry. With the continuous reduction of world oil resources, coal chemical industry has broad prospects.

Among the existing production technologies of coal chemical industry, coking is the earliest one, and it is still an important part of chemical industry.

Coal gasification plays an important role in coal chemical industry. It is used to produce all kinds of gas fuels, which is clean energy and is conducive to improving people's living standards and environmental protection. The synthesis gas produced by coal gasification is the raw material for synthesizing liquid fuel, chemical raw materials and other products.

Direct liquefaction of coal, that is, high-pressure hydrogenation liquefaction of coal, can produce artificial petroleum and chemical products. In the case of oil shortage, liquefied products of coal will replace natural oil.
