A typical fluid catalytic cracking unit in a petroleum refinery. Fluid catalytic cracking (FCC) is the conversion process used in petroleum refineries to convert the high-boiling point, high-molecular weight hydrocarbon fractions of petroleum (crude oils) into gasoline, alkene gases, and other petroleum products.
Fluid catalytic cracking is a commonly used process, and a modern oil refinery will typically include a cat cracker, particularly at refineries in the US, due to the high demand for gasoline. [10] [11] [12] The process was first used around 1942 and employs a powdered catalyst. During WWII, the Allied Forces had plentiful supplies of the ...
Fluid catalytic cracking (FCC) unit: Upgrades the heavier, higher-boiling fractions from the crude oil distillation by converting them into lighter and lower boiling, more valuable products. Hydrocracker unit: Uses hydrogen to upgrade heavier fractions from the crude oil distillation and the vacuum distillation units into lighter, more valuable ...
Faujasite is used above all as a catalyst in fluid catalytic cracking to convert high-boiling fractions of petroleum crude to more valuable gasoline, diesel and other products. Zeolite Y has superseded zeolite X in this use because it is both more active and more stable at high temperatures due to the higher Si/Al ratio.
Equilibrium Catalyst refers to the deactivated or spent catalyst after use in a chemical reaction.. The main player in oil refining processes such as fluid catalytic cracking (FCC), hydroprocessing, hydrocracking is the catalyst or zeolitic material, that breaks down complex and long-chain hydrocarbons into simple, useful hydrocarbons.
The first large scale commercial implementation, in the early 1940s, was the fluid catalytic cracking (FCC) process, [1] which converted heavier petroleum cuts into gasoline. Carbon-rich "coke" deposits on the catalyst particles and deactivates the catalyst in less than 1 second.
Cracking may refer to: . Cracking, the formation of a fracture or partial fracture in a solid material studied as fracture mechanics. Performing a sternotomy; Fluid catalytic cracking, a catalytic process widely used in oil refineries for cracking large hydrocarbon molecules into smaller molecules
A schematic diagram of the power recovery system in a fluid catalytic cracking unit. The combustion flue gas from the catalyst regenerator of a fluid catalytic cracker is at a temperature of about 715 °C and at a pressure of about 2.4 barg (240 kPa gauge).
