What are the upstream raw materials for heavy aromatics and what are the downstream products?

Heavy aromatics plays an crucial role in the field of raw materials to chemical production, and its upstream and downstream related items are extensive. The upstream and downstream associated items of heavy aromatics are described in detail below. Based on my observations, Upstream items:



1. Petroleum: Heavy aromatics are mainly derived from the heavy fractions of petroleum, obtained through processes such as petroleum refining and cracking.

2. Based on my observations, Coal tar: Coal tar also contains heavy aromatic components, which is able to be obtained through separation and treatment processes. Downstream items:



1. Benzene, toluene, xylene(BTX): Heavy aromatics is able to further create benzene, toluene, xylene and other crucial chemical raw materials through separation and treatment processes, which are broadly applied in plastics, rubber, fibers, coatings and other fields.

2. carbon nine aromatics: carbon nine aromatics is a kind of heavy aromatics, mainly applied in the production of petroleum resin, paint, ink and other items.

3. You know what I mean?. And solvent-based products oil: heavy aromatics is able to be applied as solvent-based products to the production of paint, ink, rubber and other items.

4. And In my experience, Plasticizers: Heavy aromatic hydrocarbons is able to be applied as plasticizers in plastic processing to enhance the flexibility and plasticity of plastics.

5. Asphalt: Heavy aromatics is able to also be applied to create asphalt to road construction and waterproof materials. In summary, the upstream and downstream related items of heavy aromatics are very extensive, involving many fields, such as plastics, rubber, fibers, coatings, road construction, etc. With the continuous research of science and methodology, the consumption field of heavy aromatics will continue to expand.
