Hydrocarbon conversion with dialytic separation of the catalyst from the hydrocarbon products

Claim 1

A METHOD FOR PRODUCING GASOLINE BOILING RANGE ALKYLATE WHICH COMPRISES CONTACTING IN A REACTION ZONE AN ISOPARAFFIN AND AN OLEFIN WITH A CATALYST COMPRISING BORON TRIFLUORIDE AND FERRIC PYROPHOSPHATE CONTAINING WATER OF HYDRATION AT A TEMPERATURE BETWEEN ABOUT -25* C. AND 150*C. UNDER A PRESSURE OF ABOUT 100 TO 1000 P.S.I.G., MAINTAINING A PHASE OF LIQUID HYDROCARBONS CONTAINING DISSOLVED BORON TRIFLUORIDE IN SAID REACTION ZONE, CONTACTING SAID LIQUID PHASE WITH ONE SIDE OF A PERMEATION MEMBRANE AND HYDROPHOBIC PLASTIC PERMEATING LIQUID HYDROCARBONS THROUGH SAID MEMBRANE AND OUT OF SAID REACTION ZONE INTO A ZONE OF REDUCED PRESSURE FROM WHICH THE PERMEATED MIXTURE IS RAPIDLY REMOVED, SAID PERMEATED MIXTURE COMPRISING HYDROCARONS AND BORON TRIFLUORIDE IN WHICH THE BORON TRIFLUORIDE IS PRESENT IN A LOWER CONCENTRATION THAN IN SAID REACTION ZONE, AND RECOVERING A GASOLINE BOILING RANGE ALKYLATE FROM SAID PERMEATED MIXTURE.
