Abstract: A second-stage hydrocracking catalyst is provided, comprising: a) a zeolite beta having an OD acidity of 20 to 400 μmol/g and an average domain size from 800 to 1500 nm2; b) a zeolite USY having an ASDI between 0.05 and 0.12; c) a catalyst support; and d) 0.1 to 10 wt % noble metal; wherein the second-stage hydrocracking catalyst provides a hydrogen consumption less than 350 SCFB across a range of synthetic conversions up to 37 wt % when used to hydrocrack hydrocarbonaceous feeds having an initial boiling point greater than 380° F. (193° C.). A second-stage hydrocracking process using the second-stage hydrocracking process is provided. A method to make the second-stage hydrocracking catalyst is also provided.
