Improving FCC catalyst performance - DigitalRefining

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… WebApr 15, 2016 · Catalyst sample, apparatus, and attrition tests. A commercial FCC catalyst was used in this study. It consists mainly of Y-zeolite and kaolin, and is serving in a FCC unit in China petroleum industry. Its mean particle diameter, packing density, and surface area are about 109 μm, 0.885 g/cm 3 and 168.7 m 2 /g, respectively. law firm ranking in usa
