Aromatic residual oil/residual liquid is an important raw material in the production of chemical products, and its upstream and downstream related products are widely used, mainly related to petroleum refining, organic chemical industry, polymer materials and other fields. The following are some of the main upstream and downstream related products:

1. Upstream products:
Aromatic residue/raffinate is mainly derived from the petroleum refining process, which is a by-product obtained by the cracking of hydrocarbon mixtures such as naphtha and coal tar at high temperature, high pressure and under the action of catalysts. Therefore, fossil fuels such as petroleum and coal are the main upstream raw materials for aromatic residue/raffinate.

2. Downstream products:
(1) Aromatic products: aromatic residue/raffinate rich in aromatic compounds, such as benzene, toluene, xylene, etc. These compounds are important raw materials for many organic chemicals and can be used to produce plastics, rubber, fibers, dyes, pharmaceutical intermediates, etc.
(2) Carbon black: aromatic residue/residual liquid can be used as raw material for the production of carbon black, and high-performance carbon black products can be obtained through pyrolysis or gasification processes. Carbon black can be used in tires, rubber products, inks, coatings and other fields.
(3) Fuel oil: Aromatic residue/residual liquid can be used as fuel oil for boiler combustion and power generation after further processing.
(4) Other chemical products: Aromatic residual oil/residual liquid also contains many other organic compounds, such as phenols, naphthalene, anthracene, etc., these compounds are also raw materials for many chemicals.

In short, aromatic residual oil/residual liquid has an important position in the field of chemical production raw materials, and its upstream and downstream related products are extensive, which plays an important role in promoting the development of the petrochemical industry.
