Cracking oil technology
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. Cracking, in petroleum refining, the process by which heavy hydrocarbon molecules are broken up into lighter molecules by means of heat and usually pressure and sometimes catalysts. Cracking is the most important process for the commercial production of gasoline and diesel fuel. Cracking of petroleum yields light oils Cracking is a chemical process used in oil refineries. Cracking separates large hydrocarbon molecules in raw crude oil to create byproducts such as heating oil, gasoline, liquefied petroleum gas, diesel fuel, jet fuel and other petroleum distillates. Still, thermal cracking is an important technology, and some smaller, older units in parts of the world rely on it. Both processes aim to convert less-valuable products, such as heavy fuel oil and cutter stock, into feedstock that feeds the catalytic reactor for higher-valued products and higher gasoline yields. In the reactor, the cracking reactions initiate on the active sites of the catalysts with the formation of carbocations and the subsequent ionic chain reactions produce branched alkanes and aromatic compounds to constitute the crackate (cracked gasoline with high octane number), light olefins, cycle oils, and slurry oil that are sent to the fractionator. 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 kerosene (jet fuel). Fluid catalytic cracking 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 of petroleum hydrocarbons was originally done by thermal cracking, which has been almost completely replaced by catalytic cracking because it produces more gasoline with a higher octane rating. It also prod
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. [9] [10] [11] The process was first used around 1942 and employs a powdered catalyst .

Petroleum Refinery Sector Risk and Technology Review and New Source Jul 23, 2012 biomass-derived oil processing using conventional fluid catalytic cracking (FCC), a technology responsible for producing the majority of Fundamentals of Chemical Technology and Chemicals Management In modern oil refinery industry a commonly used process is a catalytic cracking in a.
The technologies of slurry-phase hydrocracking of heavy oil and the latest development of dispersed catalysts were reviewed. Catalysts for slurry-phase hydrocracking of heavy oil have undergone two development phases, that is, heterogeneous solid powder catalysts and homogeneous dispersed catalysts.

In petrochemistry, petroleum geology and organic chemistry, cracking is the process whereby and earn foreign exchange, so their oil industry eventually did obtain much of their technology from foreign companies, largely American. Cracking, in petroleum refining, the process by which heavy hydrocarbon molecules are broken up into lighter molecules by means of heat and usually pressure gas oils into naphtha to meet the rising demand for high-octane gasoline, but it also represented a breakthrough in catalyst technology.

The episode was shown on russian news NTV on Apr 2, 2009. It describes the new non-traditional and extremely efficient oil processing technology based on recent cavitation research. Crude oil would be an ideal feedstock for directly producing olefins and aromatics. Then, direct steam cracking of crude oil has to deal with coking issues, which can be tackled by separating the heavy fraction or using solid heat carriers to retain coke , , . 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.

This program, "Fluid Catalytic Cracking Process Technology," has been developed by Refining Process Services to provide an in-depth yet practical review of current FCC technology. The refining process is also called the ‘cracking’ process. Crude oil is heated to over 370 degrees Celsius and tit is pumped into the base of the distillation tower. The crude oil vaporises and rises up the tower. As it cools the molecules condense, with heavier molecules of asphalt, bitumen and tar at the bottom
