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. 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. Cracking. Fuels made from oil mixtures containing large hydrocarbon. molecules. are not efficient as they do not flow easily and are difficult to ignite. Cracking is most often utilized to produce gasoline and jet fuel from heavy gas oils. Reforming is typically utilized on lower-value light fractions, again to produce more gasoline. The reforming process involves inducing chemical reactions under pressure to change the composition of the hydrocarbon chain.

In petrochemistry, petroleum geology and organic chemistry, cracking is the process whereby complex organic molecules such as kerogens or long-chain Cracking, in petroleum refining, the process by which heavy hydrocarbon molecules are broken up into lighter molecules by means of heat and usually pressure 29 May 2018 Cracking is a chemical process used in oil refineries. Cracking separates large hydrocarbon molecules in raw crude oil to create byproducts Steam cracking uses a higher temperature of over 800°C and no catalyst. The slideshow describes the process of catalytic cracking. The most valuable fractions for the chemical industry, and for producing petrol, are liquefied petroleum gas (LPG), naphtha, kerosine and gas oil. These are treated Cracking takes large hydrocarbons and breaks them into smaller ones. This process reduces the viscosity of heavy weight oils and produces tar. coking

Thermal cracking or simply cracking is a process of breaking down the larger and heavier nonvolatile molecules of hydrocarbons (primarily crude oil) into smaller and lighter molecules by application of heat at high temperatures and pressures in the presence of a catalyst. This process is sometimes also called pyrolysis of oil. This process includes two stages. In the first, the feedstock is blended with a catalyst to crack the long, heavy chemical chains in the crude oil. The cracked material is allowed to cool and then cycles to a unit where hydrogen attaches to it to create new chemical compounds. Catalysts and hydrogen are needed for this process, in concentrations that depend on the base composition of the feedstock.
