Abstract
A hydrocracking catalyst is provided comprising: a) greater than 10 wt % of a zeolite USY having: i. a total OD acidity of 0.350 to 0.650 mmol/g; ii. an ASDI between 0.05 and 0.15; iii. a BET surface area greater than 600 m2/g; iv. a SAR greater than 10; v. less than 45 vol % of pores greater than 2 nm; b) a support; and c) 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 using a hydrocracking catalyst to produce middle distillates is provided. A method for making a hydrocracking catalyst is also provided.
