One of the most important process stages in an oil refinery is Fluid Catalytic Cracking (FCC), also called the ‘Cat’. This process breaks down low-value, heavy hydrocarbons into lighter and more valuable hydrocarbon products. It uses a fluidized bed of fine catalyst to promote hydrocarbon cracking …
The feedstock of crude oil is a gooey mixture of various hydrocarbons which is de-salted, heated, separated and broken down big molecules of un-useable heavy product into smaller molecules of useable lighter products . The heavier products are fed into catalytic cracking or hydrocracking units to obtain gasoline, naphtha and middle distillates .
Catalytic Cracking. A catalyst allows lower reaction temperatures to be used. In fluidised catalytic cracking, the feedstock is gas oil which is vaporised and passed through a zeolite, produced as a fine powder (Unit 2), heated to about 700-800 K in the reactor.
11. A fluidized bed catalytic cracking process according to claim 10 in which cracking catalyst is loaded into the regenerator when the regenerator attains a temperature at which heat from the exothermic combustion of the coke accumulated on the catalyst during the cracking of the heavy oil feed is sufficient to sustain the cracking reaction. 12.

Cracking can be done by various methods including catalytic cracking and steam cracking. Students should be able to describe in general terms the conditions used for catalytic cracking and steam cracking. The products of cracking include alkanes and another type of hydrocarbon called alkenes. OCR Chemistry B: 21st century
Although most of the cracking reactions in the FCC are catalytic, thermal cracking reactions also occur. Thermal cracking reactions are caused by cracking severity, feedstock quality, catalyst properties, non-ideal contact of the oil and catalyst in the bottom of riser, degree of catalyst back-mixing and long residence time in the reactor housing.
During upgrading processes, heavy oils such as bunker C oil undergo the cracking process to produce high-value products like gasoline, diesel, and kerosene. Heavy oil upgrading (HOU), also called cracking, involves extracting light distillates in the crude distillation unit and adding catalyst or hydrogen to the atmospheric residue to convert ...
Integration of gas oil and light olefin catalytic cracking zones with a pyrolytic cracking zone to maximize efficient production of petrochemicals is disclosed. Integration of the units in parallel allows production of an overall product stream with maximum ethylene and/or propylene by routing various feedstreams and recycle streams to the appropriate cracking zone(s), e.g. ethane/propane to ...
use of catalyst additives based on ZSM-5. However, besides maximizing the propylene production in the reactor, a second objective should be pursued: the propylene recovery increase in the gas recovery section. In this section, the yield is affected by the gas compressor performance, the equipment design and process scheme.

Nov 14, 2015 Fluid Catalytic Cracking 8. FLUID CATALYTIC CRACKING Description a. The most common process is FCC, in which the oil is cracked in the presence of a finely divided catalyst which is maintained in an aerated or fluidized state by the oil vapors.
J.W. Thybaut, G.B. Marin, in Advances in Catalysis, 2016 5.2.2 Fuel Production From Gas Oils, FCC Cycle Oils, and Shale Oils. Hydrocracking was first applied in the early 1960s to convert low-value distillate feeds such as cycle oils and heavy gas oils to high-value gasoline products (3). In the 1970s, a broader range of hydrocracking products were targeted in order to address the shifting ...
