Diesel fuel, compared to petrol is
When crude oil is heated, then which one of the following hydrocarbon is given off first?
Crude petroleum, as obtained from the oil wells contains gases and certain impurities such as water, solids etc. The crude oil is separated into gasoline, kerosine, fuel oil etc. by the process of fractional distillation. In the first step, the petroleum is passed through a separator in which gases are removed and a product known as natural gasoline is obtained.
Polymerisation is a chemical process in which molecules of a compound become?
It is the process of converting olefins, the unsaturated products of cracking, into heavier and stable compounds.

The molecular structure of the straight-run gasoline is changed by
Reformation is a type of cracking process which is used to convert the low antiknock quality stocks into gasolines of higher octane rating. It do'es not increase the total gasoline volume.
