Gasoline hydrocracking catalyst and process

摘要

A catalyst for use in acid catalyzed chemical conversion processes such as hydrocarbon conversion processes comprises zeolite beta and a dealuminated Y zeolite having an overall silica-to-alumina mole ratio greater than 6.0, preferably LZ-210 zeolite. A preferred catalyst contains nickel and molybdenum hydrogenation components in addition to the zeolite beta and the LZ-210 zeolite and, when used in gasoline hydrocracking, is found to be more active and selective for both light and heavy gasoline than a commercially available gasoline hydrocracking catalyst containing nickel and molybdenum hydrogenation components and a single steam-stabilized Y zeolite.
