Improved noble metal zeolite catalyst for second-stage hydrocracking

摘要

A second-stage hydrocracking catalyst is provided comprising: a. from 40 wt% to 70 wt% of a zeolite USY having an ASDI from 0.05 to 0.18; b. an amorphous silica alumina; 0 c. a second alumina; and d. 0.1 to 10 wt% noble metal; wherein the second-stage hydrocracking catalyst has a BET surface area from 450 to 650 m2/g. A second-stage hydrocracking process is provided comprising using the second-stage hydrocracking catalyst to produce middle distillate. A method for making the second-stage hydrocracking catalyst is also provided. dKrcsen
