Fluid Catalytic Cracking (FCC) Cracking reactions also deposit a significant amount of coke on the catalysts, leading to the deactivation of the catalyst. After removing the adsorbed hydrocarbons by steam stripping, the coked catalyst is sent to the regeneration unit to burn off the coke with air.Catalytic uses a catalyst to speed up the cracking reaction. Catalysts include zeolite, aluminum hydrosilicate, bauxite and silicaalumina.

Fluid catalytic cracking (FCC) process is an important oil refinery process, since this process converts heavy petroleum fractions into lighter hydrocarbon products inside a reactor. In an attempt to maximize production and improve operating efficiency, a comprehensive analysis of a FCC unit regenerator Fluid catalytic cracking (FCC) is the major catalytic refinery process and the chemistry of some of the complex reactions occurring during FCC processing is reviewed and discussed. Experimental results for catalysts based on zeolite Y, and its modifications, and for comparison of zeolite Y and shapeselective catalysts are used to explain features of the underlying chemistry involved in the FCC process.fluid catalytic cracking chemical reactions All catalytic process can be classified according to reaction mechanism as: oxidationreduction reactions (redox reactions): hydrogenation, dehydrogenation, oxidation. The typical catalysts: metals, semiconducting metal oxides and sulfides. acidbase reactions: hydrolysis, isomerization, cracking

Fluid catalytic cracking is one of the most important conversion processes used in petroleum refineries. It is widely used to convert the highboiling, highmolecular weight hydrocarbon fractions of petroleum crude oils into more valuable gasoline, olefinic gases, and other products. Cracking of petroleum hydrocarbons was originally done by thermal cracking, which has been almost completely replaced by catalytic cracking fluid catalytic cracking chemical reactions Vacuum Distillation Unit. Fluid Catalytic Cracking Unit (FCC): FCC is one of the most important conversions processes used in oil refinery process. The purpose of FCC unit is to transfer heavy crude oil into light oil. Under the action of heat and catalyst, upgrades the heavier, higherboiling fractions from the crude oil distillation by converting Main Catalytic Cracking Reaction is given in Table MVI 5. 1. Main reactions involved in catalytic cracking are Cracking Isomerisation Dehydrogenenation Hydrogen transfer Cyclization Condensation Alkylation and dealkylation Major primary reactions taking place in catalytic cracking is given in Table
