Cyclic hydrocarbons; ethylbenzene

HS v2022 Code: 290260

About cyclic hydrocarbons; ethylbenzene

HS code 290260 covers the classification of cyclic hydrocarbons, including the specific compound ethylbenzene. This class of organic chemicals plays a crucial role in the production of a wide range of industrial and consumer products, from plastics and resins to fuels and solvents. As a key component in the petrochemical industry, the compounds described by this code contribute significantly to the global economy and are essential for the manufacture of many everyday items.

Production process

The primary production method for the cyclic hydrocarbons and ethylbenzene covered by HS code 290260 is catalytic reforming. This process involves the rearrangement of hydrocarbon molecules, typically from straight-chain to more complex cyclic structures, through the use of specialized catalysts. The specific techniques may vary depending on the desired output, but generally involve high temperatures, pressures, and carefully controlled reaction conditions to optimize the yield and purity of the target compounds.

Production inputs

The main inputs required for the production of the chemicals under HS code 290260 are crude oil or natural gas liquids, which serve as the primary feedstock. Additionally, the process requires specialized catalysts, typically containing metals such as platinum or rhenium, as well as various auxiliary materials like hydrogen and process heat. Sophisticated refining and separation equipment, such as distillation columns and reactors, are also essential for the efficient production of these cyclic hydrocarbons.

Production outputs

The primary outputs of the industry covered by HS code 290260 are the cyclic hydrocarbons themselves, including ethylbenzene. These compounds are then further processed and used as intermediates in the production of a wide range of other chemicals and products. For example, ethylbenzene is a key precursor for the manufacture of 290270 styrene, which is widely used in the production of plastics, resins, and synthetic rubbers. Other cyclic hydrocarbons may be used as solvents, fuel additives, or as feedstock for the production of 290330 aromatic hydrocarbon derivatives.
