Catalysts Still Going Strong

摘要

Refineries vary by complexity; more complex refineries have more secondary conversion capability, meaning they can produce different types of petroleum products. Fluid catalytic cracking (FCC), a type of secondary unit operation, is primarily used in producing additional gasoline in the refining process. Unlike atmospheric distillation and vacuum distillation, which are physical separation processes, fluid catalytic cracking is a chemical process that uses a catalyst to create new, smaller molecules from larger molecules to make gasoline and distillate fuels.
