ABSTRACT:
The selectivity of a midbarrel hydrocracking process for middle distillates is significantly increased by using a catalyst containing a Y zeolite that has been exchanged with rare earth cations. The rare earth-exchanged Y zeolite has a unit cell size below 24.45 angstroms and/or a water vapor sorptive capacity less than 10 weight percent at 25.degree. C. and a p/p.sub.o value of 0.1.
