Abstract
Abstract Disclosed is a hydrocracking catalyst comprising an alumina-zeolite support, a rare earth exchange metal component, at least one metal component selected from Group VIB or Group VIII and from about 0.1 to about 5 wt. % of at least one component selected from Group IIA based on the weight of the finished catalyst.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
111 words
In a process for hydrocracking hydrocarbons boiling above about 650° F. at a temperature in the range of about 400° F. to about 1000° F. at elevated pressures up to about 3000 psig. selectively to middle distillate hydrocarbons boiling in the range of about 350° F. to about 650° F. which comprises contacting said hydrocarbons boiling above about 650° F. with a hydrocracking catalyst composition comprising an alumina-zeolite support, a rare earth exchange metal component, at least one metal component from Group VIB or Group VIII and from about 0.1 to about 5 wt. % of at least one component from Group IIA based on the weight of the finished catalyst.
Claim 2
Dependent Claim
111 words
In a process for hydrocracking hydrocarbons boiling above about 650° F. at a temperature in the range of about 400° F. to about 1000° F. at elevated pressures up to about 3000 psig. selectively to middle distillate hydrocarbons boiling in the range of about 350° F. to about 650° F. which comprises contacting said hydrocarbons boiling above about 650° F. with a hydrocracking catalyst composition comprising an alumina-zeolite support, a rare earth exchange metal component, at least one metal component from Group VIB or Group VIII and from about 0.1 to about 5 wt. % of at least one component from Group IIA based on the weight of the finished catalyst.
