Industrial cracking carbon nine-start-up materials have an important position in the field of chemical production raw materials, and their upstream and downstream related products are extensive. The following are some common upstream and downstream related products:

1. Upstream products:

(1) Petroleum hydrocarbons: industrial cracking carbon nine-starting materials are mainly produced from petroleum hydrocarbons through cracking reaction, so petroleum hydrocarbons are the main upstream raw materials.

(2) Catalyst: The production process of cracking carbon nine-starting materials requires the use of catalysts to promote the cracking reaction. Therefore, the catalyst is also one of its upstream products.

2. Downstream products:

(1) benzene, toluene, xylene and other aromatic hydrocarbons: cracking carbon nine-drive feed contains rich aromatic hydrocarbon components, through further separation and purification, benzene, toluene, xylene and other important aromatic hydrocarbon products can be obtained.

(2) Olefins: Cracked carbon nine-start-up feed contains a certain amount of olefin components, which can be used as raw materials for the production of olefins.

(3) Gasoline, diesel and other fuel oils: Cracked carbon nine-starting materials can also be further processed to produce gasoline, diesel and other fuel oils.

(4) Carbon black: The heavy components in the cracking carbon nine-starting material can be used to produce carbon black, which is an important rubber reinforcing agent.

In short, the upstream and downstream related products of industrial cracking carbon nine-start-up materials are very extensive, involving many important chemicals and fuel oil products.
