A middle distillate hydrocracking catalyst containing zeolite USY with low acidity and large domain size, and zeolite beta

摘要

Zeolite beta having an OD acidity of 20 to 50 占 퐉 ol / g and an average crystal size of 300 to 800 nanometers; Zeolite USY wherein the wt% of the zeolite beta is less than the wt% of the zeolite USY; A support comprising amorphous silica aluminate and a second support material; And at least one metal selected from the group consisting of Group 6 elements and Group 8 to Group 10 elements of the periodic table. There is provided a process for hydrocracking a hydrocarbonaceous feedstock comprising contacting the hydrocarbonaceous feedstock with a hydrocracking catalyst under hydrocracking conditions to produce a hydrocracked effluent comprising a middle distillate. A process for preparing the present hydrocracking catalyst is also provided.
