Acyclic hydrocarbons; unsaturated, propene (propylene)

HS code 290122 covers the classification of propene (also known as propylene), a key unsaturated acyclic hydrocarbon. Propene is a colorless, flammable gas with a wide range of industrial applications, making it an important commodity chemical within the global petrochemicals industry. As a fundamental building block for various polymers and other chemicals, propene plays a vital role in the manufacturing of a diverse array of products that are essential to modern life.

Propene is primarily produced through the steam cracking of hydrocarbons, typically natural gas liquids or naphtha. This process involves heating the feedstock to extremely high temperatures, causing the larger hydrocarbon molecules to break down into smaller, more unsaturated compounds like propene. Catalytic processes, such as fluid catalytic cracking (FCC) in oil refineries, also generate propene as a by-product. Additionally, propene can be obtained through the dehydrogenation of propane, another important petrochemical feedstock.

The main inputs required for the production of propene include hydrocarbon feedstocks, such as natural gas liquids, naphtha, or propane, as well as energy in the form of heat to facilitate the cracking or dehydrogenation processes. Specialized equipment, such as steam crackers, FCC units, and dehydrogenation reactors, are also essential for the industrial-scale production of propene.

Propene is a versatile chemical that serves as a key feedstock for the production of a wide range of downstream products. It is used in the manufacture of 390210 Polypropylene, 290230 (Propene (propylene)), and various other petrochemicals and polymers. Propene is also an important intermediate in the production of 290531 (Propyl alcohol (propanol) and its isomers), 290220 Isobutene; isobutylene, and other specialty chemicals.
