What is kerosene extracted from
Kerosene, also known as fire oil, fire water, many friends hear this name also think kerosene is related to coal, is extracted from coal, but in fact it is not, kerosene is extracted from petroleum.
The main component of kerosene is the hydrocarbon element, is a hydrocarbon substance, from the substance classification, kerosene and gasoline, diesel, lubricating oil, paraffin, asphalt and other similar substances, but the molecular carbon content of the problem, but also after the extraction of crude oil fractionation extracted.
Two, how is kerosene extracted
Kerosene is a class of light petroleum products, obtained from natural or man-made petroleum by fractionation or cracking.
The refining method of kerosene is similar to gasoline, but the boiling point is different, and paraffin based crude oil is used as raw material, and the fraction is about 230℃. Or naphthenic crude oil is used as raw material, and the fraction at about 215 ° C is distilled and deeply refined to obtain kerosene.
The principle of refining kerosene is that different components of the oil boil and vaporize at different temperatures, and the kerosene vapor produced by the boiling of the kerosene components is withdrawn, and the kerosene vapor is cooled into liquid kerosene.
Can coal be extracted into kerosene
You can't.
Coal is an ancient plant buried in the ground experienced complex biochemical and physicochemical changes gradually formed solid flammable minerals, it in addition to use as a fuel, can also be extracted from other products, general coal can be extracted from gas, coal tar and coke, but can not be extracted from kerosene.
