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; 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.
