The refining process of breaking down via heat and pressure the larger, heavier and more complex hydrocarbon molecules into simpler and lighter molecules, primarily gasoline. Catalytic cracking is acc [..]

Process in which heavier hydrocarbons are converted into lighter products at high temperature (around 500°C) using a catalyst.

A method of cracking that uses a catalyst to convert hydrocarbons to positively charged carbocations, which then break down into smaller molecules. This can be carried out at much lower temperatures than thermal cracking - still hot, 500-600°C as compared to around 700°C, but that difference adds up to a lot of $$$.

A refining process for breaking down large, complex hydrocarbon molecules into smaller ones. A catalyst is used to accelerate the chemical reactions in the cracking process.

Refinery process where long and complex hydrocarbons are broken down into smaller and simpler molecules using heat and a catalyst (in a carbon rejection process at high temperatures and low pressures) [..]

Refinery process using a catalyst whereby heavy heavy gas oil is converted to about 50% gasoline and 50% gases and gas oil for recycling.

The fluidised catalytic cracking process of breaking up heavier hydrocarbon molecules into lighter hydrocarbon fractions (see Cracking)

The process of breaking up heavier hydrocarbon molecules into lighter hydrocarbon fractions by using heat and catalysts.

The process of breaking up heavier hydrocarbon molecules into lighter hydrocarbon fractions by use of heat and catalysts. See also cracking.
