“Petroleum cracking” means a unit composed of a reactor, regenerator and fractioning tower which is used to convert certain petroleum fractions into more valuable products by passing the material at elevated temperature through a bed of catalyst in the reactor. Coke deposits produced on the catalyst during cracking are removed by burning off in the regenerator.
