Fluid catalytic cracking - Wikipedia
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 of petroleum hydrocarbons was originally done by thermal cracking, which has been almost ...
Catalytic Cracking - an overview | ScienceDirect …
Catalytic cracking is an important process in the oil industry where petroleum vapor passes through a low-density bed of catalyst, which causes the heavier fractions to ‘crack’ producing lighter more valuable products. In the petrochemicals industry they are used for producing polyolefins on a very large scale. The particles consist of growing polyolefin granules (polyethylene or ...

Petroleum refining - Catalytic cracking | Britannica
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. While they succeeded in providing a small increase in gasoline yields, it was the commercialization of the fluid catalytic cracking process in ...

30.01.2019 · The catalytic converter uses precious metals and high heat to oxidize and reduce harmful emissions, converting them into safer compounds like H2O, CO2, nitrogen (N2). Because of the way they are constructed, using rare metals like platinum, palladium , and rhodium, catalytic converters are expensive, costing upwards of $1,000 (not inclusive of diagnosis and installation).

Catalytic Cracking - Set Laboratories
Catalytic cracking is similar to thermal cracking except that catalysts facilitate the conversion of the heavier molecules into lighter products. Use of a catalyst (a material that assists a stone reaction but does not take part in it) in the cracking reaction increases the yield of improved-quality products under much less severe operating conditions than in thermal cracking. Typical ...

16.07.2015 · Catalytic cracking was truly revolutionized in the early 1960s with the advent of zeolite-containing fluid cracking catalysts. Catalyst activities were raised by an order of magnitude and units needed to be redesigned to take full advantage of the new catalyst technology. These design changes included the elimination of reactor dense beds and the use of the feed riser as the sole conversion ...
