New Coal Chemical Industry

The new coal chemical industry refers to the application of clean energy and chemicals as the target products, the application of high and new technology in coal conversion, and the establishment of a future emerging coal-energy industry; combined with the development of coal resource development and coal production and construction, several large industrial bases or base groups have been built. The new coal chemical industry is the strategic direction for the coal industry to adjust the industrial structure and take the road of new industrialization.

The difference between new coal chemical industry and traditional coal chemical industry: new coal chemical industry usually refers to coal to oil, coal to methanol, coal to dimethyl ether, coal to olefin, coal to ethylene glycol, etc. Traditional coal chemical industry involves coke, calcium carbide, synthetic ammonia and other fields.

main products

The new coal chemical industry mainly produces clean energy and alternative petrochemical products, such as diesel, gasoline, aviation kerosene, and liquefied petroleum gas (see Figure 1 and Figure 2 for coal-based synthetic chemicals for the above products - indirect liquefaction of coal). Ethylene raw materials, polypropylene raw materials, methanol, dimethyl ether and unique chemical products with unique advantages of coal chemical industry, such as aromatic hydrocarbon products. (See Figure 1 for the above products). There are also electricity, heat, etc. (see Figure 2--schematic diagram of coal-based polygeneration for the above products).

Characteristics of new coal chemical industry

(1) Take clean energy as the main product. The new coal chemical industry mainly produces clean energy and alternative petrochemical products, such as diesel, gasoline, aviation kerosene, liquefied petroleum gas, ethylene raw hopper, polypropylene raw hopper, alternative fuel (methanol, Erjiatun), electricity, heat etc., as well as the unique chemical products with unique advantages of coal chemical industry, such as aromatic hydrocarbon products.

(2) Coal-energy-chemical integration. The new coal chemical industry is the strategic direction of China's energy technology development in the future. It is closely dependent on the development of coal resources and combined with other energy and chemical technologies to form an emerging industry integrating coal, energy and chemical industry.

(3) High-tech and optimized integration. According to different coal types, coal quality characteristics and target products, the new coal chemical industry adopts different high-tech coal conversion technologies, and optimizes and integrates different processes in terms of energy cascade utilization and product structure to improve overall economic benefits, such as coal coking-coal direct liquefaction combined. Co-production, coal coking-chemical synthesis co-production, coal gasification-synthesis-electric power co-production, coalbed methane development and chemical utilization, coal chemical and mineral processing co-production, etc. At the same time, the new coal chemical industry can promote the rapid development and industrialization of modern coal chemical technology from a high starting point through the extensive use of information technology.
