Answer:
Catalytic cracking is an important process in the oil industry where petroleum vapor passes through a low-density bed of catalyst, which causes the heavier fractions to 'crack' producing lighter more valuable products
Thermal cracking is an extraction process in which hydrocarbons such as crude oil are heated to a high temperature to break the molecular bonds. Thermal cracking is a refining process in which heat and pressure are used to break down, rearrange, or combine hydrocarbon molecules.
