Gas Oil is one of the products obtained by refining petroleum, a part of the petroleum boiling at about 180 ° C to 320 ° C. It is one of the blends that brings the oil to the liquor and constitutes about 10% to 25% of the total petroleum volume.
It is obtained from petroleum by fractional distillation method.
With distillation of petroleum, gasoline, diesel, light and heavy oils are obtained beside the gas oil. Steamed oil is sent to the distillation column of the required length. The product with the lowest boiling point in the oil vapor is concentrated in the traps located at the top of the column. The products with the largest boiling point are concentrated under the column. When the gasoline product is concentrated at and close to the uppermost levels of the column, the kerosene is concentrated in the middle of the column and is removed therefrom. There is continuity in fractional distillation.
There are substances in this way that cause unpleasant odors and have poor flammability.
These unwanted qualities of the gas oil are eliminated by chemical processes. Although these chemical processes are very diverse, the most common is sulfuric acid. Refined kerosene is a dull yellow or white, non-irritating odoriferous oil.
It is an oily liquid.
Although the chemical composition varies depending on the source, it is a mixture of about 10% hydrocarbon, hydrocarbons are generally molecules containing from 10 to 16 carbons. In addition, n-dodecane contains benzene alkyl derivatives, naphthalene and naphthalene derivatives.
Kerosene was first obtained in 1850 from coal tar. After 1859 it was obtained from petroleum and is still the most important source. Until the development of electrical and internal combustion engines
was an important product of petrol as lighting and engine fuel. Today it is used as fuel and solvent
. It is also used in jet engines.
Kerosene strong>, sometimes spelled kerosine strong> > or paraffin oil strong> in the United Kingdom, Hong Kong, Ireland and South Africa, is a combustible hydrocarbon liquid.
The word “Kerosene” was registered as a trademark by Abraham Gesner in 1854, and for the several years, only the North American Gas Light Company and the Downer Company (to which Gesner had granted the right) “.[2nd]
In the United Kingdom, two grades of heating oil use this name – premium kerosene (more commonly known as UK as paraffin) BS2869 Class C1, the lightest grade, which is usually used for lanterns, wick heaters, and combustion engines; and standard kerosene BS2869 Class C2, a heavier distillate, which is used as domestic heating oil. Premium Kerosene is usually sold in 5 or 20 liter containers from hardware, camping and garden stores and is often dyed purple. Standard kerosene is usually dispensed in a tanker and is colorless.
Kerosene is usually called paraffin strong> in Southeast Asia and South Africa (not to be confused with the much more viscous paraffin oil used as a laxative, or the waxy solid also called paraffin wax or just paraffin); variants of petroleum strong> in parts of Central Europe (not to be confused with crude oil to in English); 
Kerosene is widely used in the United States, Australia (where it is often referred to as “kero”) and New Zealand. jet-engined aircraft (jet fuel) and some rockets, but also commonly used as a heating fuel and for fire toys such as poi.
Diesel fuel is generally stored in yellow containers for the same reason. Share information multiplies.
