our company has ran Mineral Products Trading many years,we have close relationship with them,The relationship between mankind and chemical industry is very close, universal access to all aspects of life. In modern life, Chemical Products can not be obtained almost anytime, anywhere. From the material life such as clothing, food, shelter and transportation to the spiritual life such as culture and art, entertainment and so on, all require chemical products to serve them. Some chemical products play an epoch-making role in the history of human development. Their production and application even represent a certain historical stage of human civilization. As a category of knowledge, chemical industry has many kinds of decomposition or comprehensive classification methods in different historical periods and under different demands. According to the source of raw materials, product classification, but also in accordance with the law of history, history classification. Each division method is difficult to strictly adapt.

This volume seeks to reduce unnecessary crossings, a comprehensive classification of methods designed from the raw materials of fuel chemical branches; from the product of inorganic chemicals, basic organic chemicals, polymer chemicals, fine chemicals and other branches; from the common The branch of chemical engineering proceeding from the regularity of the process, and the comprehensive branch proceeding from historical development and horizontal linkages. Fuel chemical raw materials are oil, natural gas, coal and oil shale and other combustible minerals, so it is divided into petroleum refining industry, petrochemical, natural gas chemical, coal chemical and shale oil industry.

      Among them, the oil refining industry is to create a higher output value of the industrial sector is the country's important economic lifeline. Natural gas is often symbiotic with petroleum and natural gas chemical industry is often attributed to petrochemical industry. At this stage, oil refining and petrochemicals are the main fuel chemical industry. Products produced by the fuel and chemical industries include fuels and chemical raw materials, which are mainly organic chemical raw materials (except for the syngas used in the production of inorganic chemicals such as synthetic ammonia). Therefore, the petrochemical industry is also a major part of the basic organic chemical industry.
