Information about gasoline
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. Kerosene has a high boiling point and is safe to use when ignited. It has become the main product of crude oil refining, while gasoline and other components are usually burned as fuel.
By the middle and late19th century, the internal combustion engine using gasoline was successfully manufactured, and 1886 gasoline engine was successfully used as automobile power. Therefore, the importance of gasoline is increasing day by day. However, crude oil distillation can only extract 20% gasoline, and 19 1 year American Standard Oil Company solved the problem of low gasoline output.
The pyrolysis process invented by William Burton and Robert Humphries is used to pyrolyze heavy gas oil into light gasoline and other fractions, thus improving the gasoline yield as a whole. The thermal cracking process was authorized by American patent in 19 13, and the subsequent catalytic cracking process was more than thermal cracking, which further improved the gasoline yield and higher octane number.
