How is gasoline made?

Preparation of gasoline:

Gasoline is produced by fractional distillation of crude oil and cracking of heavy fractions.

Distillation, catalytic cracking, thermal cracking, hydrocracking, catalytic reforming, alkylation and other units of the crude oil processing process produce gasoline components, but the octane number is different, such as direct-distillation gasoline octane number is low, can not be used as a separate engine fuel; in addition, the impurities of sulfur content is also different, so the gasoline components of the sulfur content of the gasoline components need to be desulfurized and refined, and after that, the above gasoline components to be blended, if necessary, need to add high-octane components, and then add a high octane component. After that, the above gasoline components are blended, and if necessary, high-octane components are added to finally obtain gasoline products that meet the national standards.

. p>Use Classification:

Gasoline is one of the most used light petroleum products and is an important fuel for engines.

Based on the manufacturing process, gasoline components can be classified as straight-run gasoline, thermally cracked gasoline (coker gasoline), catalytically cracked gasoline, catalytically reformed gasoline, stacked gasoline, hydrocracked gasoline, alkylated gasoline, and synthetic gasoline.

Gasoline products can be divided into three major categories, namely aviation gasoline, automotive gasoline and solvent gasoline, according to their applications. The first two are mainly used as fuel for gasoline engines and are widely used in automobiles, motorcycles, speedboats, helicopters, and aircraft used in agriculture and forestry. Solvent gasoline is used in the production of synthetic rubber, paint, grease, spices, etc.; gasoline components can also dissolve oil and other water insoluble substances, play a role in cleaning oil; gasoline components as an organic solution, but also can be used as an extractant.
