Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
105 words
A process for the conversion of olefins to distillate and the range (C 10 +) hydrocarbons, said process comprising contacting an olefin feed with a high SiO 2 /Al 2 O 3 ratio large pore crystalline aluminosilicate zeolite catalyst at a pressure in the range of from about 200 psig to about 2000 psig and at a conversion temperature in the range of from about 200°-750° F. and weight hourly space velocity of about 20 to 0.1 wherein the large pore crystalline aluminosilicate zeolite catalyst has pore dimensions of greater than about 6 angstroms and a constraint index of about 0.5 to less than 2.
Claim 2
Dependent Claim
105 words
A process for the conversion of olefins to distillate and the range (C 10 +) hydrocarbons, said process comprising contacting an olefin feed with a high SiO 2 /Al 2 O 3 ratio large pore crystalline aluminosilicate zeolite catalyst at a pressure in the range of from about 200 psig to about 2000 psig and at a conversion temperature in the range of from about 200°-750° F. and weight hourly space velocity of about 20 to 0.1 wherein the large pore crystalline aluminosilicate zeolite catalyst has pore dimensions of greater than about 6 angstroms and a constraint index of about 0.5 to less than 2.
Claim 3
Dependent Claim
24 words
A process as defined in claim 1 wherein said feed comprises an olefin, a mixture of olefins or a mixture of olefins and paraffins.
Claim 4
Dependent Claim
31 words
