Gasoline is produced by "breaking down" the larger hydrocarbons in crude oil into smaller ones with between 3-12 carbon atoms. Crude oil contains a wide range of hydrocarbons, organometallics and other compounds containing sulfur, nitrogen and other impurities. The hydrocarbons can contain up to 60 carbon atoms.
A refinery distills crude oil into various fractions and, depending on the desired final products, will further process and blend those fractions. Typical final products can consist of compressed natural gases, liquefied petroleum gases, butane, gasoline, kerosene, diesels, distillate and residual fuel oils, lubricating oils, paraffin oils and waxes.
