Cracking (chemistry) - Wikipedia

In petrochemistry, petroleum geology and organic chemistry, cracking is the process whereby complex organic molecules such as kerogens or long-chain hydrocarbons are broken down into simpler molecules such as light hydrocarbons, by the breaking of carbon-carbon bonds in the precursors. The rate of cracking and the end products are strongly dependent on the temperature and presence of catalysts.

Part 13: Catalytic Cracking - FQE Chemicals

Cracking is a process in which large hydrocarbon molecules are broken up "cracked" into smaller, more valuable hydrocarbon molecules. As the name implies, the catalytic cracking process takes place in the presence of a catalyst. The catalyst promotes breaking of the large molecules in a certain way that maximizes the yield of gasoline.
