Reforming C9 is an important raw material in the production of chemicals, mainly from the reforming process of petroleum refining. C9 aromatics is a mixture, mainly containing benzene, toluene, xylene and other aromatic components. Therefore, the upstream and downstream associated products of the reformed C9 are mainly related to the aromatics industry chain. The following are some of the main upstream and downstream related products:

1. Upstream products:

(1) Petroleum: Reforming C9 is mainly derived from the reforming process of petroleum refining, so petroleum is the main upstream raw material for reforming C9.

(2) Catalyst: A catalyst is used in the reforming process to promote the reforming reaction of hydrocarbon molecules. Therefore, the catalyst is also one of the upstream products of reforming C9.

2. Downstream products:

(1) Benzene: Benzene is one of the main components in the reforming C9 and can be used to produce chemicals such as styrene, aniline, and benzoic acid.

(2) Toluene: Toluene is also one of the main components in reforming C9 and can be used to produce chemicals such as phenol, cresol, and methyl isobutyl ketone.

(3) Xylene: Xylene is another major component in the reforming C9, which can be used to produce chemicals such as para-xylene and ortho-xylene, which can further produce plastic products such as PET and EPS.

(4) Ethylene: Reforming C9 can be used as a cracking raw material to produce ethylene through steam cracking. Ethylene is an important raw material in the petrochemical industry and can be used to produce chemicals such as polyethylene, ethylene propylene rubber, and ethylene glycol.

(5) carbon nine aromatic resin: reforming C9 can also be further processed to produce carbon nine aromatic resin, the resin has good corrosion resistance, heat resistance, oxidation resistance and other properties, can be used to make coatings, adhesives, waterproof materials.

In short, the upstream and downstream related products of the reformed C9 are very extensive, involving petrochemicals, plastics, rubber, coatings and other fields.
