Description

Gasoline is a mixture of about **0 chemicals refined from crude oil. Its usually a colorless, light brown or pink liquid. Gasoline is used in cars, boats, motorcycles, lawn mowers and other engines. Gasoline usually contains additives affecting the way it burns.

Gasoline is most often produced by the fractional distillation of crude oil. The crude oil is separated into fractions according to different boiling points of hydrocarbons of varying chain lengths. This fractional distillation process yields approximately *5% of straight-run gasoline from each barrel of crude oil.

The yield of gasoline may be doubled by converting higher or lower boiling point fractions into hydrocarbons in the gasoline range.
