Summary: | To provide a catalyst with activity and selectivity that are required to optimize production of middle distillates in hydrocracking.SOLUTION: Provided is a hydrocracking catalyst which comprises: a. 0.5 to 10 wt.% zeolite beta having an OD acidity of 36-400 μmol/g and an average domain size of 800 to 1500 nm2; b. 0 to 5 wt.% zeolite USY having an ASDI between 0.05 and 0.12; where the weight percentage of the zeolite beta is greater than the weight percentage of the zeolite USY; c. a catalyst support; and d. at least one metal selected from the group consisting of elements from Group 6 and Groups 8-10 of the periodic table. A process for hydrocracking using the hydrocracking catalyst to produce middle distillates is provided. A method for making the hydrocracking catalyst is also provided.SELECTED DRAWING: None
