Fluid Catalytic Cracking (FCC) in Petroleum Refining
Email: 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. After providing some general background of the FCC process, including a short history as well as details on the process, reactor design, chemical reactions involved and catalyst material, we will discuss several trends in FCC catalysis research by focusing on ways to improve the zeolite structure stability, propylene selectivity and the overall catalyst accessibility by a the addition of rare earth elements and phosphorus, b constructing hierarchical pores systems and c the introduction of new zeolite structures. In addition, we present an overview of the state-of-the-art micro-spectroscopy methods for characterizing FCC catalysts at the single particle level.
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. - Just what are you doing when having extra time?

Handbook of Petroleum Processing pp Cite as. The catalytic cracking process, commercialized in , has undergone numerous changes. It is the most important refinery process in that it converts the heavy portion of the crude barrel into transportation fuels. The main changes in catalysts, equipment and operations are covered along with the versatility of the process to handle a wide variety of feeds and produce the desired products. Skip to main content.
