Fluid catalytic cracking technology and operations pdf
Fluid catalytic cracking - WikipediaEmail: ln. Fluid catalytic cracking FCC is one of the major conversion technologies in the oil refinery industry. FCC currently produces the majority of the world's gasoline, as well as an important fraction of propylene for the polymer industry. In this critical review, we give an overview of the latest trends in this field of research. These trends include ways to make it possible to process either very heavy or very light crude oil fractions as well as to co-process biomass-based oxygenates with regular crude oil fractions, and convert these more complex feedstocks in an increasing amount of propylene and diesel-range fuels.

Fluid catalytic cracking FCC is one of the most important conversion processes used in petroleum refineries. It is widely used to convert the high-boiling, high-molecular weight hydrocarbon fractions of petroleum crude oils into more valuable gasoline , olefinic gases, and other products. It also produces byproduct gases that have more carbon-carbon double bonds i. This portion of crude oil is often referred to as heavy gas oil or vacuum gas oil HVGO. In the FCC process, the feedstock is heated to a high temperature and moderate pressure, and brought into contact with a hot, powdered catalyst. The catalyst breaks the long-chain molecules of the high-boiling hydrocarbon liquids into much shorter molecules, which are collected as a vapor. Oil refineries use fluid catalytic cracking to correct the imbalance between the market demand for gasoline and the excess of heavy, high boiling range products resulting from the distillation of crude oil.
Refineries vary by complexity; more complex refineries have more secondary conversion capability, meaning they can produce different types of petroleum products.
