Polymerization and alkylation of hydrocarbons

Claim 2

A PROCESS FOR THE SELECTIVE REMOVAL OF A 1-OLEFIN FROM A MIXTURE OF HYDROCARBONS COMPRISING A 1-OLEFIN HAVING FROM 3 TO 8 CARBON ATOMS PER MOLECULE AND NO BRANCHING NEARER THE DOUBLE BOND THAN THE 4-POSITION IN ADMIXTURE WITH A DIFFERENT OLEFIN, WHICH PROCESS COMPRISES CONTACTING SAID MIXTURE WITH A CHROMIUM OXIDE CATALYST COMPRISING CHROMIUM OXIDE ASSOCIATED WITH AT LEAST ONE MEMBER OF THE GROUP CONSISTING OF SILICA, ALUMINA, ZIRCONIA DN THORIA, SAID CATALYST HAVING BEEN TREATED TO IMPART POLYMERIZATION ACTIVITY THERETO, SELECTIVELY POLYMERIZING SAID 1-OLEFIN TO HIGH POLYMER, AND RECOVERING A RESULTING MIXTURE SUBSTANTIALLY DEPLETED WITH RESPECT TO 1-OLEFIN.

Claim 3

AN ALKYLATION PROCESS WHICH COMPRISES CONTACTING A MIXTURE COMPRISING A 1-OLEFIN, A 2-OLEFIN, AND AN ISOPARAFFIN AND BEING COMPOSED OF HYDROCARBONS HAVING FROM 3 TO 5 CARBON ATOMS PER MOLECULE, AT A TEMPERATURE IN THE RANGE OF 150 TO 250*F. WITH A CATALYST CONSISTING ESSENTIALLY OF FROM 0.1 TO 30 WEIGHT PERCENT CHROMIUM IN THE FORM OF CHROMIUM OXIDE OF WHICH AT LEAST A PART OF THE CHROMIUM IS IN THE HEXAVALENT STATE, ASSOCIATED WITH AT LEAST ONE MEMBER OF THE GROUP CONISTING OF SILICA, ALUMINA, ZIRCONIA AND THORIA, EFFECTING A SELECTIVE CONVERSION OF SAID 1-OLEFIN TO HIGH POLYMER, RECOVERING SAID HIGH POLYMER, RECOVERIONG A HYDROCARBON MIXTURE SUBSTANTIALLY DEPLETED WITH RESPECT TO SAID 1-OLEFIN, AND SUBJECTING THE DEPLETED MIXTURE TO ALKYLATION CONDITIONS OF TEMPERATURE, PRESSURE AND CONTACT TIME IN THE PRESENCE OF A STOICHIOMETRIC EXCESS OF ALKYLATABLE ISOPARAFIN WITH RESPECT TO OLEFINS AND IN THE PRESENCE OF AN ALKYLATION CATALYST, AND RECOVERING A RESULTING ALKYLATE.

Claim 4

AN ALKYLATION PROCESS WHICH COMPRISES CONTACTING A MIXTURE COMPRISING A 1-OLEFIN, A 2-OLEFIN, AND AN ISOPARAFFIN AND BEING COMPOSED OF HYDROCARBONS HAVING FROM 3 TO 5 CARBON ATOMS PER MOLECULE, AT A TEMPERATURE IN THE RANGE OF 150 TO 250*F. WITH A CATALYST CONSISTING ESSENTIALLY OF FROM 0.1 TO 30 WEIGHT PERCENT CHROMIUM IN THE FORM OF CHROMIUM OXIDE OF WHICH AT LEAST A PART OF THE CHROMIUM IS IN THE HEXAVALENT STATE, ASSOCIATED WITH AT LEAST ONE MEMBER OF THE GROUP CONISTING OF SILICA, ALUMINA, ZIRCONIA AND THORIA, EFFECTING A SELECTIVE CONVERSION OF SAID 1-OLEFIN TO HIGH POLYMER, RECOVERING SAID HIGH POLYMER, RECOVERIONG A HYDROCARBON MIXTURE SUBSTANTIALLY DEPLETED WITH RESPECT TO SAID 1-OLEFIN, AND SUBJECTING THE DEPLETED MIXTURE TO ALKYLATION CONDITIONS OF TEMPERATURE, PRESSURE AND CONTACT TIME IN THE PRESENCE OF A STOICHIOMETRIC EXCESS OF ALKYLATABLE ISOPARAFIN WITH RESPECT TO OLEFINS AND IN THE PRESENCE OF AN ALKYLATION CATALYST, AND RECOVERING A RESULTING ALKYLATE.
