The many hydrocarbons in crude oil may be separated into fractions, each of which contains molecules with a similar number of carbon atoms by fractional distillation
The fractions can be processed to produce fuels and feedstock for the petrochemical industry
Many of the fuels on which we depend for our modern lifestyle, such as petrol, diesel oil, kerosene, heavy fuel oil and petroleum gases, are produced from crude oil
Many useful materials are produced by the petrochemical industry such as solvents lubricants polymers and detergents
the vast array of natural and synthetic carbon commons occur due to the ability of carbon atoms to form families of similar compounds
