Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
63 words
A process for converting feedstock comprising C 3 + olefins to product comprising non-aromatic hydrocarbons of higher molecular weight than feedstock olefins and aromatic hydrocarbons comprising contacting said feedstock in the absence of added hydrogen at conversion conditions with a catalyst comprising a crystalline zeolite having a Constraint Index of less than about 2 and a silica/alumina mole ratio greater than about 100.
Claim 2
Dependent Claim
63 words
A process for converting feedstock comprising C 3 + olefins to product comprising non-aromatic hydrocarbons of higher molecular weight than feedstock olefins and aromatic hydrocarbons comprising contacting said feedstock in the absence of added hydrogen at conversion conditions with a catalyst comprising a crystalline zeolite having a Constraint Index of less than about 2 and a silica/alumina mole ratio greater than about 100.
Claim 3
Dependent Claim
18 words
The process of claim 1 wherein said feedstock comprises olefins of from 3 to about 6 carbon atoms.
Claim 4
Dependent Claim
22 words
The process of claim 2 wherein said olefins are selected from the group consisting of propylene, butenes, pentenes, hexenes and mixtures thereof.
