Coal is an important fossil energy, and its rich energy has always been valued by people. However, in addition to combustion as an energy source, coal can also be diversified through coal chemical technology.

coal chemical industry, as the name suggests, is the utilization technology of converting coal resources into various chemicals. Through different chemical reactions, the molecular structure of coal is transformed into chemical products with high added value.

From the current coal chemical technology, there are four different types of technical routes. The first is a syngas route based on gasification, which mainly prepares some hard chemicals, such as methanol and dimethyl ether. The second is a liquid fuel route based on direct coal liquefaction (DTL), which mainly produces liquefied hydrocarbon fuels, such as diesel and aviation kerosene. The third is a liquid fuel route based on indirect coal liquefaction (ITL), which mainly prepares synthetic petroleum products, such as gasoline and diesel. The fourth is the synthetic chemical route represented by synthetic ammonia, which mainly prepares some high value-added chemicals, such as synthetic ammonia and urea.

coal chemical technology occupies a very important position in the chemical industry. In addition to effectively improve energy efficiency, but also achieved very significant economic and environmental benefits. It is mainly reflected in three aspects: first, it can achieve large-scale production, ensuring lower production costs; second, the diversified use of coal, improving the comprehensive utilization of resources; third, coal chemical products with its good quality and stable price competitive advantage, has been widely recognized by the market.

the same, coal chemical technology can also solve some environmental problems. The use of coal chemical technology can greatly reduce the generation of pollutants such as coal crosstalk, ash and sulfur, and effectively reduce the level of environmental pollution such as air, water and soil.

In general, the development of coal chemical technology caters to the comprehensive requirements of economic development and environmental protection needs, and has become an indispensable part of the chemical industry. We should understand and support the development of coal chemical technology, and realize the win-win situation of comprehensive utilization of resources and environmental protection.
