Middle distillate hydrocracking catalyst highly containing stabilized y zeolite with enhanced acid site distribution

Abstract

To provide an improved hydrocracking catalyst containing a stabilized Y zeolite (SY) having an enhanced acid site distribution as compared to conventional SY zeolites.SOLUTION: A hydrocracking catalyst comprises: a support; an amorphous silica alumina material; an SY zeolite having an acid site distribution index factor between 0.02 and 0.12; and at least one metal selected from the group consisting of elements from Group 6 and Groups 8-10 of the Periodic Table. Preferably, the SY zeolite is a high nanopore volume (HNPV) SY zeolite having a nanopore volume in the 20 nm to 50 nm range of 0.15 to 0.6 cc / g.SELECTED DRAWING: Figure 3
