n: one of a group of solid. liquid, or semisolid materials that are predominantly mixtures of heavy hydrocarbons and their non-metallic derivatives and are obtained either from natural bituminous deposits or from the residues of petroleum refining.
n: gas that is a by-product of refining liquid hydrocarbons in a catalytic cracker.
n: 1. the breaking down of low temperatures and pressures.2. a motor gasoline refining process in which heavy hydrocarbon components are broken down into light hydrocarbon components using catalysts and relatively low temperatures and pressures. It produces a gasoline that has a higher octane rating and a lower sulphur content than that produced by thermal cracking.
n: the process of breaking down large chemical compounds into smaller compounds under the influence of heat or catalysts. In petroleum refining, the two major types of cracking are thermal cracking and
