Abstract
A hydrocracking catalyst is provided comprising: a zeolite beta having an OD acidity of 20 to 50 μmol/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.
