Claims Analysis
Total Claims: 23
Claim 1
Independent Claim
78 words
A process for the catalytic cracking of a high metals content charge stock which comprises contacting said charge stock under catalytic cracking conditions with a catalyst composition comprising a cracking catalyst having high activity and, as a separate and distinct entity, a diluent of little cracking activity having a MAT Activity below about 1.0 selected from the group consisting of magnesium-containing clay minerals and containing at least one metal selected from the group consisting of antimony and tin.
Claim 2
Dependent Claim
78 words
A process for the catalytic cracking of a high metals content charge stock which comprises contacting said charge stock under catalytic cracking conditions with a catalyst composition comprising a cracking catalyst having high activity and, as a separate and distinct entity, a diluent of little cracking activity having a MAT Activity below about 1.0 selected from the group consisting of magnesium-containing clay minerals and containing at least one metal selected from the group consisting of antimony and tin.
Claim 3
Dependent Claim
