Low level of chemical products extracted from coal tar in China

At present, the coking industry is deeply trapped by overcapacity, high costs, and low profits, and the loss is nearly 1/3. On June 5, Yang Wenbiao, secretary general of the China Coking Industry Association, said in an interview with reporters that chemical product recycling and comprehensive utilization of by-products The coking industry can enhance profitability, especially the deep processing of coal tar has great potential for development. China is a large country with coal tar resources. However, at present, China has a low level of extraction of chemical products from coal tar, and it must go through a centralized and large-scale processing road, establish a joint development system, and upgrade its technological level.

Yang Wentao introduced that coal tar is a very complex mixture of chemical components, and modern methods such as separation and distillation can be used to obtain precious and scarce coking chemical products and achieve greater economic benefits. China has abundant coal tar resources. By the end of 2011, the annual processing capacity of coal tar in the coking industry in China has reached more than 16 million tons, accounting for 60% of the world's total production of coal tar. Coal tar contains more than 400 chemical products and is an important raw material for chemical, steel, non-ferrous smelting, pharmaceutical, pesticide, aviation, and marine industries. Many of these compounds are valuable raw materials for the defense industry, and some of them are also difficult for petrochemical companies to produce and replace.

At present, some developed countries in the world have focused on the processing of coal tar to extract fine chemical products. For example, Germany Lutger's annual processing capacity of coal tar reaches 1.1 million tons, and more than 200 kinds of refined chemical products are produced from coal tar, which is the highest in the world. The better domestic companies can only extract more than 40 kinds of chemical products.

Yang Wenxuan pointed out that the centralized and large-scale processing of coal tar is the basis for the in-depth development of coal tar and the key to the development of scarce resources contained in coal tar. To promote the large-scale development of China's coal tar companies, and build several world-class coal tar processing companies that can compete with major companies such as Coopers of the US, Rutgers of Germany, Nippon Chemicals Co., Ltd., and Jiefuyi Co., Ltd. The only way to achieve coking power.
