Kerosene

From Academic Kids

Kerosene, gas oil, or paraffin (not the same as the waxy solid of that name) is a colorless flammable hydrocarbon liquid. It is obtained from the fractional distillation of petroleum at 150 C and 275 C (carbon chains from the C12 to C15 range). At one time it was widely used in kerosene lamps but it is now mainly used as a fuel for jet engines (more technically Avtur, Jet-A, Jet-B, JP-4 or JP-8). A form of kerosene known as RP-1 is burned with liquid oxygen as rocket fuel. The name kerosene is derived from the Greek word keros (κερωσ, wax).

Typically, kerosene directly distilled from crude oil requires some treatment, either in a Merox unit or a hydrotreater, to reduce its sulfur content and its corrosiveness. Kerosene can also be produced by a hydrocracker, which is used to upgrade the parts of crude oil that would otherwise only be good for fuel oil.

Its use as a cooking fuel is mostly restricted to less developed countries, where it is usually less refined and contains impurities and even debris. It can also be used to remove lice from hair, but stings and can be dangerous on skin.

Jet engine fuel is kerosene that meets more stringent specifications, particularly the smoke point and the freeze point.

Kerosene and other paraffins were first discovered by Carl Reichenbach.
