Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
97 words
A process for converting a C 2 -C 10 hydrocarbon feed consisting essentially of paraffins, olefins or their mixtures comprising contacting a charge thereof with a zeolite-containing catalyst, said zeolite having a silica to alumina ratio of at least about 12 and a constraint index of from about 1 to about 12, and containing from about 0.1% to about 5% by weight of zinc and from about 0.1% to 2% by weight of another metal selected from the group consisting of metals of Groups IB and VIII of the Periodic Table, germanium, rhenium and rare earth metals.
Claim 2
Dependent Claim
97 words
A process for converting a C 2 -C 10 hydrocarbon feed consisting essentially of paraffins, olefins or their mixtures comprising contacting a charge thereof with a zeolite-containing catalyst, said zeolite having a silica to alumina ratio of at least about 12 and a constraint index of from about 1 to about 12, and containing from about 0.1% to about 5% by weight of zinc and from about 0.1% to 2% by weight of another metal selected from the group consisting of metals of Groups IB and VIII of the Periodic Table, germanium, rhenium and rare earth metals.
