Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
101 words
A process to convert C 2 -C 3 olefin to gasoline blending stock products comprising contacting C 2 -C 3 olefin with an AMS-1B crystalline borosilicate catalyst composition which is in the hydrogen form or onto which has been placed one or more catalytically active materials selected from the group consisting of copper, lanthanum and zinc at a temperature of about 300° to about 500° C., a pressure of about 2 to about 40 atomospheres, a hydrogen to hydrocarbon molar ratio of 0.1 to about 10 and a weight hourly space velocity of about 0.3 to about 5 hr -1 .
Claim 2
Dependent Claim
101 words
A process to convert C 2 -C 3 olefin to gasoline blending stock products comprising contacting C 2 -C 3 olefin with an AMS-1B crystalline borosilicate catalyst composition which is in the hydrogen form or onto which has been placed one or more catalytically active materials selected from the group consisting of copper, lanthanum and zinc at a temperature of about 300° to about 500° C., a pressure of about 2 to about 40 atomospheres, a hydrogen to hydrocarbon molar ratio of 0.1 to about 10 and a weight hourly space velocity of about 0.3 to about 5 hr -1 .
Claim 3
Dependent Claim
24 words
