Petroleum refining Catalytic cracking Britannica

Petroleum refining Petroleum refining Catalytic cracking: The use of thermal cracking units to convert gas oils into naphtha dates from before 1920. These units produced small quantities of unstable naphthas and large amounts of by-product coke. While they succeeded in providing a small increase in gasoline yields, it was the commercialization of the fluid catalytic cracking process in

Chemistry of Catalytic Cracking FSC 432: Petroleum Refining

Chemistry of Catalytic Cracking. As opposed to thermal cracking governed by free radicals, catalytic cracking proceeds through the formation of ionic species on catalyst surfaces, and produces shorter, but branched-chain (not straight-chain) alkanes by cracking the long straight-chain alkanes.

Fluid catalytic cracking Wikipedia

Dec 26, 2005 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 point, high-molecular 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

Catalyst attrition during fluid catalytic cracking

Fluid catalytic cracking (FCC) is a process which converts heavy fractions of petroleum oil to lighter products which are in greater demand. Modern FCC catalysts consist of zeolite in a porous matrix. These catalyst particles are mechanically degraded by attrition which leads to the generation of fines.

Jan 01, 2020 It is the most flexible process in the petroleum refinery. It can process all types of feedstock. Its cracking severity can be adjusted greatly. Since the start-up of the first commercial FCC unit in 1942, many improvements have been made to enhance the unit’s mechanical reliability and its ability to crack heavier, lower-value feedstocks.

Cracking (chemistry) Wikipedia

In petrochemistry, petroleum geology and organic chemistry, cracking is the process whereby complex organic molecules such as kerogens or long-chain hydrocarbons are broken down into simpler molecules such as light hydrocarbons, by the breaking of carbon-carbon bonds in the precursors. The rate of cracking and the end products are strongly dependent on the temperature and presence of catalysts.
