Abstract: A catalyst system has been designed that disrupts the sedimentation process. The catalyst system achieves this by saturating key feed components before the feed components are stripped into their incompatible aromatic cores. The efficacy of this disruptive catalyst system is particularly evident in a hydrocracker configuration that runs in two-stage-recycle operation. The catalyst is a self-supported multi-metallic catalyst prepared from a precursor in the hydroxide form, and the catalyst must be toward the top level of the second stage of the two-stage system.

Abstract: Described herein is a hydrocracking catalyst and process that may be used to make middle distillates and unconverted oil having beneficial yield and product characteristics. The process generally comprises contacting a hydrocarbon feed with the hydrocracking catalyst under hydrocracking conditions to produce a product comprising middle distillates and unconverted oil products. The hydrocracking catalyst comprises an SSZ-91 molecular sieve and a modifying metal selected from one or more Group 6 metals, and, optionally, one or more Group 8 to 10 metals, or a modifying metal selected from Group 8 to 10 metals and combinations thereof, and, optionally, one or more Group 6 metals. The hydrocracking catalyst may comprise a matrix material and/or an additional zeolite.
