Fluid catalytic cracking in the oil & gas industry

Cracking of long chain hydrocarbons

Fluid catalytic cracking (FCC) is a process where the long chain hydrocarbon molecules in the lighter gas oil streams from the distillation columns are broken down into shorter molecules. In this way the feedstock produces mainly gasoline (known as petrol in Europe), and not diesel. Where there is a high demand for diesel fuel, this FCC process would not be used.
