Abstract
Abstract A process for converting synthesis gas composed of hydrogen and carbon monoxide to hydrocarbons. The process includes the step of contacting at reaction conditions a synthesis gas feed to a catalyst which includes cobalt in catalytically active amounts up to about 60 wt % of the catalyst and rhenium in catalytically active amounts of about 0.5 to 50 wt % of the cobalt content of the catalyst supported on alumina. A metal oxide promoter may be added.

Claims Analysis
Total Claims: 17
Claim 1
Independent Claim
66 words
A process for the production of hydrocarbons comprising the step of contacting a synthesis gas feed comprised of hydrogen and carbon monoxide over a catalyst comprised of cobalt and rhenium composited on an alumina support wherein rhenium is present in relatively lesser amounts than the cobalt content of the catalyst, at a temperature, gaseous hourly space velocity and a pressure useful for promoting a Fischer-Tropsch Synthesis.
Claim 2
Dependent Claim
66 words
A process for the production of hydrocarbons comprising the step of contacting a synthesis gas feed comprised of hydrogen and carbon monoxide over a catalyst comprised of cobalt and rhenium composited on an alumina support wherein rhenium is present in relatively lesser amounts than the cobalt content of the catalyst, at a temperature, gaseous hourly space velocity and a pressure useful for promoting a Fischer-Tropsch Synthesis.
Claim 3
Dependent Claim
19 words
The process recited in claim 1 wherein the temperature is in the range of about 150° to 325° C.
Claim 4
Dependent Claim
19 words
The process recited in claim 1 wherein the pressure is in the range of about 1 to 100 atmospheres.
Claim 5
Dependent Claim
33 words
The process recited in claim 1 wherein the gaseous hourly space velocity in the range of about 0.1 to 50 m 3 of synthesis gas per kilogram of catalyst per hour is employed.
