|
How does catalytic cracking works? |
Heat the long chain hydrocarbons to vaporise them (turn them into a gas) The vapour is the passed over a hot, powdered catalyst Aluminium oxide is one of the catalysts used The long chain molecules split apart or 'crack' on the surface of the specks of catalyst |
