Claim 1
Independent Claim
119 words
THE PROCESS FOR THE SELECTIVE HYDROGENATION OF OLEFINIC HYDROCARBONS OF A DRIPOLLENE CHARGE STOCK IN TWO REACTION ZONES WHICH CONSISTS ESSENTIALLY OF VAPORIZING THE CHARGE STOCK WITH 700 TO 1100*F. HYDROGEN CONTAINING GAS, CONTACTING THE RESULTING VAPORIZED MIXTURE OF CHARGE STOCK AND HYDROGEN CONTAINING GAS IN THE FIRST REACTION ZONE WITH SULFIDED COBALT MOLYBDATE CATALYST AT A TEMPERATURE BETWEEN 300 TO 900*F., ADJUSTING THE TEMPERATURE OF THE EFFLUENT FROM THE FIRST REACTION ZONE BEFORE SAID EFFLUENT ENTERS A SECOND REACTION ZONE SO THAT THE REACTION TEMPERATURE IN THE SECOND REACTION ZONE IS MAINTAINED BELOW A MAXIMUM OF 900*F. AND CONTACTING THE TEMPERATURE ADJUSTED EFFLUENT FROM THE FIRST REACTION ZONE WITH SULFIDED COBALT MOLYBDATE CATALYST IN THE SECOND REACTION ZONE.
