Q

Explain the process of cracking…

A

Cracking is TD reaction - breaking molecules down by heating them. The first step is heat long-chain hydrocarbon to vaporise it. The vapour is passed over powered catalyst at a temperature of about 400 - 700. Aluminium oxide is catalyst used. The long-chain molecules split apart on the surface of specks of catalyst.
