Obtaining useful substances from crude oil (cracking)

Cracking (type of thermal decomposition) Hydrocarbons can be cracked (decomposed) to produce smaller, more useful molecules. There are two types of cracking process that achieve thermal decomposition: catalytic cracking and thermal cracking. Catalytic cracking: the alkane is heated and the vapour is passed over a hot zeolite (aluminosilicate) catalyst. The reaction occurs at around 500ºC. Thermal (steam) cracking: the alkane vapour
