Modified zeolite second stage hydrocracking catalyst and use of thereof for hydrocarbon conversion

摘要

A hydrocracking catalyst, containing a USY zeolite modified by treatment with an organic acid to remove aluminum, an alumina binder, two or more metals selected from metals of Groups VIB and VIII, and cerium in the range of 0.1 to 5.0 wt %. A method of making the hydrocracking catalyst, whereby a USY zeolite is treated with an organic acid to remove aluminum from the zeolite structure and subsequently impregnating with a rare earth metal of the Lanthanide series to form a modified USY zeolite. The modified USY zeolite is mixed with alumina comprising a peptizing agent and impregnated with two or more metals selected from metals of Groups VIB and VIII.

1. A hydrocracking catalyst, comprising: a USY zeolite modified by treatment with an organic acid to remove aluminum; an alumina binder; two or more metals selected from metals of Groups VIB and VIII; and cerium in the range of 0.1 to 5.0 wt. %; wherein the USY zeolite has an acidity ranging from 0.86-0.99 mmol/g.
