Abstract: A silica-alumina based composite material for making hydroprocessing catalysts, is disclosed. The silica-alumina composite material generally comprises at least two silica-aluminas, the first being a modified first silica-alumina, and the second being a second silica-alumina that is unmodified or modified. The first silica-alumina is modified to comprise silica and alumina domains and a silica-alumina interphase. The second silica-alumina may also be modified at the same time or separately to comprise silica and alumina domains and a silica-alumina interphase. The first silica-alumina and the second silica-alumina differ in one or more physical and/or chemical characteristics, e.g., the ratio of silica to alumina, surface area, pore size, pore volume, silica domain size, or alumina domain size. The invention can be used for making catalyst base materials and catalysts useful for upgrading hydrocarbon feedstocks to produce fuels, lubricants, chemicals and other hydrocarbonaceous compositions.

Abstract: Provided is a novel catalyst for use in the second stage of a two-stage hydrocracking process. The present process comprises hydrocracking a hydrocarbon feed in a first stage. The catalyst in the first stage is a conventional hydrocracking catalyst. The product from the first stage can then be transferred to a second hydrocracking stage. The catalyst used in the second stage of the present hydrocracking process comprises a base impregnated with metals from Group 6 and Groups 8 through 10 of the Periodic Table, and an organic acid. The base of the catalyst used in the present second hydrocracking stage comprises alumina, an amorphous silica-alumina (ASA) material, and a USY zeolite. Improved naphtha production is achieved.

Abstract: Bimetallic platinum-palladium hydrocracking catalysts are disclosed. The bimetallic catalyst generally comprises a base material comprising an alumina, an amorphous silica-alumina, and a Y zeolite, and a bimetallic platinum-palladium modifier metal composition dispersed on and/or impregnated within the base material. The catalyst is useful as a hydrocracking catalyst for hydrocarbon feedstocks, including as a second stage catalyst to produce fuels, and more particularly to produce higher yields of jet fuels.
