Name the catalyst used in catalytic cracking
WitrynaCommon catalysts are Cu catalyst, noble metal catalyst, and Ni catalyst [3], [5]. Among them, the Ni catalyst is widely used due to its relatively low cost and high redox activity [6] . Whereas, most catalysts are supported on Al 2 O 3 , which contributes to the disadvantages of poor dispersion and less catalytic activity site on the surface [7] .

Name the catalyst used in catalytic cracking
Did you know?
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, olefinic gases, and other petroleum products. The cracking of petroleum hydrocarbons was originally done by thermal cracking, now virtually replaced by catalytic cracking, which yields greater volumes of high octane rating gasoline; and produces by-product gases, with more carbo… Witryna5 sty 2016 · Catalytic cracking. 1. Introduction. Zeolites are widely used as catalysts in industry. Zeolite Y is a crystalline microporous aluminosilicate with a typical framework pore of 0.74 nm and a supercage of 1.3 nm [1]. The microporosity of zeolite Y plays an important role in its shape selectivity [2], [3], [4].
