, CRUDE OIL
Crude oil is found in the Earth’s crust and is the remains of organi

Most hydrocarbons in crude oil are those called alkanes.
Crude oil is an important source of fuels such as petrol, diesel and

petrochemical industry.
Feedstock = raw material used to provide reactants for an industrial reacti
such as ethene being used to make polyethene.
