1. A hydrocracking process for making middle distillate product and unconverted oil, comprising
contacting a hydrocarbon feed with a hydrocracking catalyst under hydrocracking conditions to produce a product comprising middle distillates and unconverted oil;
wherein, the hydrocracking catalyst comprises an SSZ-91 molecular sieve, one or more Group 6 metals selected from Mo, W, or a combination thereof, and one or more Group 8 to 10 metals selected from Ni, Co, or a combination thereof;
wherein,
the hydrocracking catalyst excludes noble metal;
the middle distillate product comprises diesel fuel having a lower cloud and pour point as compared with a diesel product produced using a hydrocracking catalyst that does not include an SSZ-91 molecular sieve;
the middle distillate yield in the 380-700° F. range is at least about 55 wt. %; and,
the unconverted oil product comprises unconverted oil having a lower viscosity index and/or a lower viscosity as compared with an unconverted oil product produced using a hydrocracking catalyst that does not include an SSZ-91 molecular sieve.
