Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
131 words
In a hydrocracking process for converting a hydrocarbon feed, at least 70% of which boils within the range of 650° to about 1050° F, to liquid products boiling in the range of C 5 + to 700° F., which process comprises contacting said feed and gaseous hydrogen at elevated pressure with a hydrocracking catalyst under hydrocracking conditions, the improvement which comprises: contacting said feed with a hydrocracking catalyst composition comprising a hydrogenation component, a crystalline aluminosilicate cracking component having the essential X-ray diffraction pattern of Zeolite Beta, said crystalline aluminosilicate being further characterized by the presence of 0.5 wt % to about 4.0 wt % of framework boron and a silica to alumina ratio of at least about 35, and a solid source of alumina, whereby the catalyst life is extended.
Claim 2
Dependent Claim
