ABSTRACT:
This invention provides an improved hydrocracking catalyst which includes an inorganic oxide component, such as alumina, a hydrogenation component, such as a base metal or a noble metal and a zeolite component which is a Y-zeolite. The catalyst in this invention is particularly characterized in that the zeolite component of the catalyst has a number average crystal size of less than about 0.5 micron, preferably less than about 0.4 micron. In the process aspect of this invention the use of the above catalyst in hydrocracking processes provides improved liquid fraction yields, particularly yields of high octane gasoline, diesel fuel and premium quality jet fuel. The catalyst also produces a corresponding decrease in production of light gases, while providing no significant increase in coking or decrease in catalyst life. In another aspect this invention provides a Y-type zeolite having an average crystal size of less than about 0.5 micron which comprises less than about 0.5 wt. % alkaline metal oxide and which contains an effective amount of oxometallic cations positioned in the beta-cages of the zeolite to substantially stabilize the zeolite against the thermal degradation.
