Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
55 words
A PROCESS FOR THE SELECTIVE REMOVAL OF CARBON MONOXIDE FROM AN OLEFIN-CONTAINING HYDROCARBON STREAM WITHOUT SUBSTANTIAL REDUCTION IN THE OLEFIN CONTENT OF SAID STREAM WHICH COMPRISES PASSING SAID STREAM AT A TEMPERATURE OF AT LEAST ABOUT 300* F . INTO CONTACT WITH AN ALKALIZED IRON OXIDE-CHROMIUM OXIDE PURIFICATION AGENT WHICH HAS BEEN REDUCED IN HYDROGEN.
Claim 2
Dependent Claim
55 words
A PROCESS FOR THE SELECTIVE REMOVAL OF CARBON MONOXIDE FROM AN OLEFIN-CONTAINING HYDROCARBON STREAM WITHOUT SUBSTANTIAL REDUCTION IN THE OLEFIN CONTENT OF SAID STREAM WHICH COMPRISES PASSING SAID STREAM AT A TEMPERATURE OF AT LEAST ABOUT 300* F . INTO CONTACT WITH AN ALKALIZED IRON OXIDE-CHROMIUM OXIDE PURIFICATION AGENT WHICH HAS BEEN REDUCED IN HYDROGEN.
Claim 3
Dependent Claim
107 words
A PROCESS FOR THE POLYMERIZATION OF AN ETHYLENECONTAINING STREAM OF HYDROCARBONS ALSO CONTAINING CARBON MONOXIDE WHICH COMPRISES PASSING SAID STREAM AT A TEMPERATURE IN THE APPROXIMATE RANGE 300-680* F., A PRESSURE IN THE APPROXIMATE RANGE 100-1000 P. S. I. G., AND A SPACE VELOCITY IN THE APPROXIMATE RANGE 500-2000 VOLUMES OF GAS PER VOLUME OF TREATING AGENT PER HOUR INTO CONTACT WITH AN ALKYLIZED IRON OXIDE-CHROMIUM OXIDE TREATING AGENT WHICH HAS BEEN REDUCED IN HYDROGEN, RECOVERING A STREAM AND THEN SUBJECTING THE SAID RECOVERED MONOXIDE CONTENT AND THEN SUBJECTING THE SAID RECOVERED STREAM OF HYDROCARBONS UNDER POLYMERIZATION CONDITIONS TO THE ACTION OF A NICKEL OXIDE-SILICA-ALUMINA POLYMERIZATION CATALYST.
Claim 4
Dependent Claim
