Industrial cracking carbon nine in the field of chemical production raw materials has an important position, its upstream and downstream related products are extensive. This paper will detail the upstream and downstream related products of cracking carbon nine, including upstream raw materials and downstream products.

1. upstream raw material

1. Petroleum hydrocarbons: cracking carbon nine is mainly derived from the cracking process of petroleum hydrocarbons. Common petroleum hydrocarbon feedstocks include naphtha, light diesel oil, etc.
2. Catalytic cracking gasoline: Catalytic cracking gasoline is one of the important raw materials for cracking carbon nine, through the catalytic cracking process, large molecules of hydrocarbons can be cracked into small molecules of hydrocarbons, and then get the cracking carbon nine.

2. Downstream Products

1. Aromatic products: Cracking carbon nine is rich in aromatic components, through further separation and purification, can obtain a variety of aromatic products, such as benzene, toluene, xylene and so on. These aromatic products are widely used in plastics, rubber, fibers, dyes and other fields.
2. alkylate oil: Cracked carbon nine can be used as the raw material of alkylate oil. Through alkylation reaction, high octane gasoline blending components can be produced to improve the quality of gasoline.
3. Carbon black: Cracked carbon nine can be used as the raw material for the production of carbon black. Through the process of pyrolysis or gasification, different grades of carbon black products can be produced for tires, plastics, inks and other fields.
4. Fuel oil: Cracking carbon nine can also be further processed into fuel oil as a fuel for industrial furnaces, ships and other equipment.

In short, the upstream and downstream related products of industrial cracking carbon nine are extensive, involving many fields, such as petroleum processing, chemical industry, rubber, plastics, etc. Understanding the upstream and downstream related products of cracking carbon nine will help enterprises to better plan the production process, improve the utilization efficiency of resources, reduce costs, and also help to promote the green development of the chemical industry.
