Modification of alkanes by cracking
explain the economic reasons for cracking alkanes.
Cracking involves breaking C–C bonds in alkanes.
Thermal cracking takes place at high pressure and high temperature and produces a high percentage of alkenes (mechanism not required).
Catalytic cracking takes place at a slight pressure, high temperature and in the presence of a zeolite catalyst and is used mainly to produce motor fuels and aromatic hydrocarbons (mechanism not required).
