Abstract: This invention relates to hydrocracking catalysts utilizing stabilized aggregates of small primary crystallites of zeolite Y that are clustered into larger secondary particles. At least 80% of the secondary particles may comprise at least 5 primary crystal lites. The size of the primary crystallites may be at most about 0.5 micron, or at most about 0.3 micron, and the size of the secondary particles may be at least about 0.8 micron, or at least about 1.0 μim. The silica to alumina ratio of the resulting stabilized aggregated Y zeolite may be 4: 1 or more. This invention also relates to the use of such catalysts in hydrocracking processes for the conversion of heavy oils into lighter fuel products. The invention is particularly suited for the selective production of diesel range products from gas oil range feedstock materials under hydrocracking conditions.

Abstract: This invention relates to the composition, method of making and use of a hydrocracking catalyst that is comprised of a new Y zeolite which exhibits an exceptionally low small mesoporous peak around the 40 A (angstrom) range as determined by nitrogen adsorption measurements. The hydrocracking catalysts of invention exhibit improved distillate yield and selectivity as well as improved conversions at lower temperatures than conventional hydrocracking catalysts containing Y zeolites. The hydrocracking catalysts herein are particularly useful in the hydrocracking processes as disclosed herein, particularly for conversion of heavy hydrocarbon feedstocks such as gas oils and vacuum tower bottoms and an associated maximization and/or improved selectivity of the distillate yield obtained from such hydrocracking processes.
