Abstract: This invention relates to methods and processes for increasing the production of FCC (Fluid Catalytic Cracking) gasoline products, and optionally distillate products, from refinery feedstocks. In particular, the processes include hydrotreating and further hydroisomerizing a typical FCC range feedstream prior to catalytically cracking the feedstream in the FCC unit. The methods herein result in higher FCC naphtha yields and lower FCC cat bottoms yields thereby significantly increasing the overall FCC gasoline production for a given operating unit and increasing the profit margin of such FCC unit operations.

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: A method of rejuvenating a deactivated molecular sieve catalyst, deactivated by use in an olefin oligomerization or aromatics alkylation process, which method comprises contacting the deactivated catalyst with a stream of rejuvenation gas comprising a hydrocarbon product fraction from the process at an elevated temperature and pressure for a time sufficient to effect an increase in catalytic activity of the deactivated catalyst.

Abstract: Hydrocarbon feedstocks are hydroprocessed in reaction systems including at least one catalyst stage containing bulk metallic catalysts comprised of a Group VIII metal, a Group VIB metal, and an organic compound-based component. The catalysts are prepared by a method wherein precursors of both metals are mixed and interacted with at least one organic acid, such as glyoxylic acid, dried, heated, and sulfided. The catalysts are used for hydroprocessing, particularly hydrodesulfurizaton and hydrodenitrogenation, of hydrocarbon feedstocks.

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.
