1. In the19th century, people didn't realize the importance of gasoline. At that time, kerosene was widely used for lighting. At that time, petroleum refining relied on a simple distillation process to separate components with different boiling points from petroleum. Kerosene has a high boiling point and is safe to use when igniting. It has become the main product of crude oil refining, while gasoline and other components are usually burned as fuel. /kloc-in the middle and late 9th century, the internal combustion engine using gasoline was successfully manufactured, and 1886 gasoline engine was successfully used as the power of automobiles. Therefore, the importance of gasoline is increasing day by day. But only 20% gasoline can be extracted from crude oil by distillation. 19 1 1 year, in order to solve the problem of low gasoline yield, American Standard Oil Company adopted the thermal cracking process invented by William Burton and Robert Humphries to pyrolyze heavy gas oil into light gasoline and other fractions, which improved the gasoline yield as a whole. The thermal cracking process 19 13 was obtained in the United States. The subsequent catalytic cracking process further improved the gasoline yield and higher octane number than the thermal cracking process.

Secondly, the prepared gasoline is made from crude oil fractionation and heavy distillation decomposition. In the process of crude oil processing, distillation, catalytic cracking, thermal cracking, hydrocracking, catalytic reforming, alkylation and other devices all produce gasoline components, but the octane number is different, for example, straight-run gasoline has a low octane number and cannot be used as engine fuel alone; In addition, the sulfur content of impurities is also different, so it is necessary to desulfurize and refine the gasoline components with high sulfur content, then blend the above gasoline components and add high octane number components if necessary, and finally get the gasoline products that meet the national standards.

Three. Usage Classification Gasoline is one of the most commonly used light petroleum products and an important fuel for engines. According to the manufacturing process, gasoline components can be divided into straight-run gasoline, thermal cracking gasoline (coking gasoline), catalytic cracking gasoline, catalytic reforming gasoline, superimposed gasoline, hydrocracking gasoline, alkylated gasoline and synthetic gasoline. Gasoline products can be divided into aviation gasoline, automobile gasoline and solvent gasoline according to their uses. The first two kinds are mainly used as fuels for gasoline engines, which are widely used in automobiles, motorcycles, speedboats, helicopters, agricultural and forestry planes and so on. Solvent gasoline is used to produce synthetic rubber, paint, grease and perfume. Gasoline components can also dissolve oil stains and other water-insoluble substances, and play a role in cleaning oil stains; As an organic solution, the gasoline component can also be used as an extractant.
