Catalytic cracking describes a refining process by which certain crude cuts are broken down or cracked into simpler hydrocarbon compounds at the molecular level by means of extreme heat, pressure, and exposure to a chemical catalyst.

Catalyst is defined as a chemical which, under certain conditions, stimulates a chemical reaction (i.e. molecular change) in another compound without being consumed in the reaction.
