Fluid Catalytic Cracking (FCC) Fluid Catalytic Cracking (FCC) is a critical refining process used to convert heavy, high-boiling petroleum fractions into lighter, more valuable products such as gasoline, diesel, and olefins. The process involves breaking down large hydrocarbon molecules in the presence of a catalyst at high temperatures. The catalyst, typically a fine powder, is fluidized by the flow of hydrocarbons and steam, creating a fluid-like mixture that enhances the cracking reaction. Af
