Cracking processes Cracking is, as already explained, a process used to convert heavy hydrocarbon fractions obtained by vacuum distillation into a mixture of lighter and more useful products (fig. 4). Catalytic Cracking In catalytic cracking, the feedstock undergoes a chemical breakdown, under controlled heat (450 to 50 °C)
The used (spent) catalyst is thus routed from Petroleum Refinery Enforcement Manual Catalytic Cracking 3/80 the reactor to a regenerator where the catalyst is partially restored by burning the coke off in a controlled combustion reaction.
In petrochemistry, petroleum geology and organic chemistry, cracking is the process whereby complex organic molecules such as kerogens or longchain hydrocarbons are broken down into simpler molecules such as light hydrocarbons, by the breaking of carboncarbon bonds in the precursors. The rate of cracking and the end products are strongly dependent on the temperature and presence of catalysts.

After modifying Houdry''s techniques, in April 1936 SoconyVacuum transformed a thermalcracking unit at Paulsboro into a unit that used the Houdry process. In just under a year a new unit was processing 15,000 petroleum barrels a day. At the 1938 meeting of the American Petroleum Institute industry insiders sat up and took notice.

Bayshore Petroleum Corp. new heavy oil bitumen upgrading technology using catalyst Bayshore is a company in developing heavy oil / bitumen to light oil (diesel quality) upgrading technology using proprietary catalyst. The technology uses high efficiency liquid catalyst under low pressure, without the addition of hydrogen. Temperatures less than 420 degree C, are used to upgrade the bitumen ...
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.
The formation of branchedchain alkanes, or isoalkanes, leads to the production of gasoline with high octane numbers. This is the fundamental reason why catalytic cracking has replaced thermal cracking as the central process in a refinery geared to maximize gasoline production.

offers 2,502 petroleum cracking products. About 1% of these are pipe fittings, 1% are catalysts. A wide variety of petroleum cracking options are available to you, such as free samples. There are 2,499 petroleum cracking suppliers, mainly located in Asia.
Dec 12, 2016· Cracking is a process in which large hydrocarbon molecules are broken up "cracked" into smaller, more valuable hydrocarbon molecules. As the name implies, the catalytic cracking process takes place in the presence of a catalyst. The catalyst promotes breaking of the large molecules in a certain way that maximizes the yield of gasoline.
The fluid catalytic cracking process is a very complex and demanding one. This program, "Fluid Catalytic Cracking Process Technology," has been developed by Refining Process Services to provide an indepth yet practical review of current FCC technology.
