煤焦 油的密度及燃点?

Coking also known as the high temperature carbonization of coal. Coal as raw material, in the absence of air conditions, heated to about 950 ° C, produced by the high temperature carbonization coke, gas, coal tar and recovery of a coal conversion processes of other chemical products. The main purpose of the coke iron, a small amount as a chemical raw material to manufacture calcium carbide electrode. Coal tar is a black viscous oily liquid, which contains benzene, phenol, naphthalene, anthracene, phenanthrene and other important chemical raw materials, they are the raw material of pharmaceuticals, pesticides, explosives, dyes and other industries, after appropriate treatment can be separated one. Coking is an important part of China's chemical industry.Coking way of scientific development is the scientific development concept as a guide, as the driving force of reform and opening up, as the cornerstone of sustainable development as a means to improve the scientific and technological innovation, market-oriented, and consider China's coal, oil, natural gas, coal seamgas, coke oven gas and other fossil resources and renewable resources of scientific and rational, efficient use of direction, so that our product areas, the formation of the petrochemical and coking combination with their respective advantages complementary, formed on the whole in line with China's national conditions, scientific and rationalstructure of raw materials, product structure, technical structure and corporate structure, and enhance international competitiveness, accelerate the modernization of the chemical industry.
