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 crystallites. 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 ?m. 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: One exemplary embodiment can be a catalyst for catalytic reforming of naphtha. The catalyst can have a noble metal including one or more of platinum, palladium, rhodium, ruthenium, osmium, and iridium, a lanthanide-series metal including one or more elements of atomic numbers 57-71 of the periodic table, and a support. Generally, an average bulk density of the catalyst is about 0.300-about 0.620 gram per cubic centimeter, and an atomic ratio of the lanthanide-series metal:noble metal is less than about 1.3:1. Moreover, the lanthanide-series metal can be distributed at a concentration of the lanthanide-series metal in a 100 micron surface layer of the catalyst less than about two times a concentration of the lanthanide-series metal at a central core of the catalyst.

Abstract: A process and apparatus are disclosed for hydrocracking hydrocarbon feed in a hydrocracking unit and hydrotreating a diesel product from the hydrocracking unit in a hydrotreating unit. The hydrocracking unit and the hydrotreating unit share the same recycle gas compressor. A make-up hydrogen stream may also be compressed in the recycle gas compressor. A warm separator separates recycle gas and hydrocarbons from diesel in the hydrotreating effluent, so fraction of the diesel is relatively simple. The warm separator also keeps the diesel product separate from the more sulfurous diesel in the hydrocracking effluent, and still retains heat needed for fractionation of lighter components from the low sulfur diesel product.

Abstract: A process is disclosed for hydroprocessing two hydrocarbon streams at two different pressures. A hydrogen stream is compressed and split. A first split compressed stream is further compressed to feed a first hydroprocessing unit that requires higher pressure for operation. A second split compressed stream is fed to a second hydroprocessing unit that requires lower pressure. Recycle hydrogen from the second hydroprocessing unit is recycled back to the compression section.

Abstract: Integrated isomerization and ionic liquid catalyzed alkylation processes may comprise integrating ionic liquid alkylation and n-butane isomerization using a common distillation unit for separating an n-butane containing fraction from at least one of an alkylation hydrocarbon phase from an ionic liquid alkylation reactor and an isomerization hydrocarbon stream from an isomerization unit. The n-butane containing fraction may undergo isomerization to provide an isomerization reactor effluent comprising the isomerization hydrocarbon stream. An isobutane containing fraction, separated from at least one of the alkylation hydrocarbon phase and the isomerization hydrocarbon stream, may be recycled from the distillation unit to the ionic liquid alkylation reactor.

Abstract: This invention relates to the composition, method of making and use of a fluidized catalytic cracking (“FCC”) catalyst that is comprised of a new Y zeolite which exhibits an exceptionally low small mesoporous peak around the 40 ? (angstrom) range as determined by nitrogen adsorption measurements. FCC catalysts made from this new zeolite exhibit improved rates of heavy oil cracking heavy oil bottoms conversions and gasoline conversions. The fluidized catalytic cracking catalysts herein are particularly useful in fluidized catalytic cracking (“FCC”) processes for conversion of heavy hydrocarbon feedstocks such as gas oils and vacuum tower bottoms.

Abstract: A process for removing a nitrogen compound from a fuel feed, such as vacuum gas oil or diesel fuel, wherein the process includes contacting the fuel feed comprising the nitrogen compound with a fuel-immiscible caprolactamium ionic liquid to produce a fuel and fuel-immiscible caprolactamium ionic liquid mixture, and separating the mixture to produce a vacuum gas oil or a diesel effluent having a reduced nitrogen content relative to the vacuum gas oil or diesel feed. The invention provides an alternate use for caprolactamium ionic liquid that is produced in large quantities for the manufacture of caprolactam.

Abstract: The present invention is a process for desulfurizing hydrocarbon feedstreams with alkali metal compounds and regenerating the alkali metal compounds via the use of a transition metal oxide. The present invention employs the use of a transition metal oxide, preferably copper oxide, in order to convert spent alkali metal hydrosulfides in the regeneration of the alkali hydroxide compounds for reutilization in the desulfurization process for the hydrocarbon feedstreams. Additionally, in preferred embodiments of the processes disclosed herein, carbonates which may be detrimental to the overall desulfurization process and related equipment are removed from the regenerated alkali metal stream.

Abstract: Hydrocarbon feedstreams are desulfurized using an alkali metal reagent, optionally in the presence of hydrogen. Improved control over reaction conditions can be achieved in part by controlling the particle size of the alkali metal salt and by using multiple desulfurization reactors. After separation of the spent alkali metal reagent, the resulting product can have suitable characteristics for pipeline transport and/or further refinery processing.

Abstract: A quenching medium is delivered directly to selected regions or locations within a catalyst bed in a hydroprocessing reactor vessel in order to control the reactivity of a hydroprocess occurring in the selected regions or locations separately from other regions or locations. Temperature sensors for providing temperature indications and conduits for delivering the quench medium are distributed throughout the catalyst bed. One or more conduits can be selected for delivery of the quenching medium to selected regions or locations so that separate control of the level of reactivity in each of various regions or locations throughout the bed can be achieved.
