Kerosene or paraffin oil (British English, not to be confused with the waxy solid also called paraffin wax or just paraffin) is a colorless flammable hydrocarbon liquid. The name is derived from Greek "keros" (κηρός wax).
Its heating value, or heat of combustion, is around 18,500 Btu/lb, or 43.1 MJ/kg, making it similar to that of diesel. It is widely used to power jet-engined aircraft, but is also commonly used as a heating fuel.
Distillation
Kerosene is obtained from the fractional distillation of petroleum at 150 °C and 275 °C (carbon chains from the C12 to C15 range).
Kerosene was first refined from a naturally-occurring asphaltum called Albertite by Abraham Gesner in 1846, founding the modern petroleum industry in the process. Gesner went on to establish his Kerosene Gaslight Company to market kerosene around the world in 1850. Scottish chemist James Young built the first truly commercial oil-works in the world at Bathgate in 1851, using oil extracted from locally mined Torbanite, shale and bituminous coal. Polish chemist Ignacy Łukasiewicz discovered the means of refining kerosene from the less expensive seep oil in 1856. The widespread availability of cheaper kerosene was the principal factor in the precipitous decline in the whaling industry in the mid- to late 19th century, as the leading product of whaling was oil for lamps.
Interesting that it replaced whale oil - a great patch lube in it's day.
