MIDDLE DISTILLATE HYDROCRACKING CATALYST CONTAINING ZEOLITE USY, AND ZEOLITE BETA WITH LOW ACIDITY AND LARGE DOMAIN SIZE

摘要

A hydrocracking catalyst is provided comprising: a zeolite beta having an OD acidity of (20) to (50) μmοl/g and an average crystal size from (300) to (800) nanometers; a zeolite USY; wherein a wt% of the zeolite beta is less than the wt% of the zeolite USY; a support comprising an amorphous silica aluminate and a second support material; and at least one metal selected from the group consisting of elements from Group (6) and Groups (8) through (10) of the Periodic Table. A process for hydrocracking a hydrocarbonaceous feedstock is provided, comprising: contacting the hydrocarbonaceous feedstock with the hydrocracking catalyst under hydrocracking conditions to produce a hydrocracked effluent that comprises middle distillates. A method for making the hydrocracking catalyst is also provided.
