“…Thus, high activity in terms of conversion (recovery of more useful gasoline products from the feedstock), less residuum and insignificant amount of coke formation can be obtained by employing the zeolites as catalyst. [9,10,11,12] Catalytic cracking has a number of advantages. By catalytic cracking, high yields of gasoline with the high octane number are produced.…”

Prototype of FCC catalyst were formulated by mixing the stabilised Y zeolites (68wt%) with polyvinal alcohol (PVA) (7%) as a solution binder and bentonite (25%). The Y zeolite including the original HY with Si/Al of 2.6 (cat.-2.6) and dealuminated HY with Si/Al of 30 (cat.-30) were used and tested for catalytic cracking of Iraqi vacuum gas oil (VGO) obtained from Al-Dura refinery using a pilot plant. The cracking process was carried out at a temperature of 520 °C and atmospheric pressure, The weight ratio of catalyst / oil ratio was 3 and 5. The results show that higher conversion of 77 wt. % and better product distribution (gasoline, kerosene and gas oil) could be obtained over cat.30 resulting to a good liquid product yield. The catalytic activity, in terms of VGO conversion was not affected over cat.-30 in spite of its lower acidity, suggesting the determinate of mesoporosity in the Y zeolite (cat.-30) catalysed cracking reactions. A higher yield of ~ 67 wt% to mid-distillates (i.e.Naphtha and kerosene) was as a result of the improvements in the diffusion to and from catalyst structure.

“…Among all the zeolites used in the industry, Y-zeolite receives significant attention due to its three-dimensional pore structure and 0.74 nm diameter. Y-zeolite is extensively used in oil refining as a major part of the FCC catalyst as it provides more active sites as well as greater surface area [8][9][10]. With time, more research has been focused to synthesize new zeolites having extra-large pores for the replacement of Y-zeolite as an active part of the FCC catalyst.…”

Fluidized catalytic cracking of vacuum gas oil is considered a promising factor in enhancing the gasoline yield to fulfill global energy demands. In this study, a series of FCC catalysts with a zeolite to matrix ratio varying from 18 to 50 was prepared using USY zeolite and amorphous matrix. The matrix was composed of amorphous silica-alumina, kaolin, and silica sol binder. All fresh catalysts were subjected to hydrothermal deactivation treatment at 750 °C for 5 h. The performance evaluation of FCC catalysts was conducted in a fixed bed microactivity test unit, with vacuum gas oil as feed at 550 °C. Comparing a steamed CAT01 sample with a fresh CAT01, the surface area of the steamed sample was 23.3% less. Similarly, the fresh sample CAT05 acidity increased by 102% when compared with the fresh CAT01 sample. As the zeolite to matrix ratio increased, the selectivity of dry gas, LPG, and coke increased, associated with a consistent decrease in gasoline and heavy ends (LCO and HCO). The combined selectivity of product gasoline and LCO with low-zeolite steamed catalyst (CAT01) was 82%, and that of high-zeolite steamed catalyst (CAT05) was 76%. Furthermore, coke selectivity for the steamed CAT01 was 2.1%, whereas 3.7% was observed for the steamed CAT05 sample. The effect of the zeolite to matrix ratio was less pronounced in steamed catalysts as compared with fresh catalysts.
