Catalytic cracking process of crude oil
The American Chemical Society designated the development of the Houdry process for catalytic cracking by Eugene Jules Houdry as a National Historic Chemical Landmark at the Marcus Hook Refinery of the Sun Company (now Sunoco Logistics Partners L.P.) in Marcus Hook, Pennsylvania, on April 13, 1996. The plaque commemorating the development reads: 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, higher-boiling fractions from the crude oil distillation by converting them into lighter and lower boiling, more valuable products like The source of the large hydrocarbon molecules is often the naphtha fraction or the gas oil fraction from the fractional distillation of crude oil (petroleum). These fractions are obtained from the distillation process as liquids, but are re-vaporised before cracking. There isn't any single unique reaction happening in the cracker. The fluid catalytic cracking - a hot, fluid catalyst (1000 degrees Fahrenheit / 538 degrees Celsius) cracks heavy gas oil into diesel oils and gasoline. hydrocracking - similar to fluid catalytic cracking, but uses a different catalyst, lower temperatures, higher pressure, and hydrogen gas. It takes heavy oil and cracks it into gasoline and Fluidized bed catalytic cracking Up‐flow dense phase particulate solid process credited to W.K.

To process high-acid crude oil by catalytic cracking technology, a coupled process (FCD–FCC) involving fluid catalytic deacidification (FCD) of high-acid crude oil over a spent catalyst and fluid catalytic cracking (FCC) of heavy oil over a regenerated catalyst was proposed. Experiments were carried out in a confined fluidized bed reactor to test the feasibility of this process. The results

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. 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, high-molecular weight hydrocarbon fractions of petroleum crude oils into more valuable gasoline, olefinic gases, and other products. Catalytic Cracking Processes Print Increasing demand for gasoline, along with the need to produce high-octane gasoline for increasingly more powerful spark ignition engines, led to the development and maturation of catalytic cracking processes just before and during World War II. Catalysts used in the cracking of crude oil are usually hydrated aluminum silicates. Zeolites, or molecular sieves, are hydrated aluminosilicates having a very porous crystalline structure, in which water molecules are trapped.
Carbon is deposited on the catalyst during the cracking process. This carbon, known as catalyst coke, adheres to the catalyst, reducing its ability to crack the oil. The coke on the spent catalyst is burned off, which reheats the catalyst to add heat to the FCC process.

Main Difference – Thermal Cracking vs Catalytic Cracking. Petroleum refining is the processing of crude oil in order to obtain desired products. There are several petroleum refining processes that are helpful in converting crude oil into useful products. Catalytic Cracking. Catalytic cracking is an ionic process involving carbonium ions (hydrocarbon ions having a positive charge on a carbon atom) and are produced by: (1) addition of a proton from an acid catalyst to an olefin, (2) abstraction of a hydride ion (H−) from a hydrocarbon by the acid catalyst or by another carbonium ion. To process high-acid crude oil by catalytic cracking technology, a coupled process (FCD–FCC) involving fluid catalytic deacidification (FCD) of high-acid crude oil over a spent catalyst and fluid catalytic cracking (FCC) of heavy oil over a regenerated catalyst was proposed. Experiments were carried out in a confined fluidized bed reactor to test the feasibility of this process.
