A METHOD FOR TREATING AN ALKYLATABLE HYDROCARBON CONTAINING POLYMER FORMING CONTAMINANTS SELECTED FROM THE GROUP CONSISTING OF DIOLEFINS, ACETYLENE, ACETYLENE HOMOLOGS AND MIXTURES THEREOF, WHICH COMPRISES CONTACTING SAID HYDROCARBON WITH A SOLID POLYMERIZATION CATALYST IN A CONVERSION ZONE AT A TEMPERATURE BETWEEN ABOUT 200*F. AND ABOUT 450*F., A PRESSURE BETWEEN ABOUT 10 P.S.I.G. AND ABOUT 250 P.S.I.G., TO CONVERT THE CONTAMINANTS TO HIGHER BOILING POLYMERS, REMOVING PRODUCTS OF REACTION FROM SAID CONVERSION ZONE, COOLING SAID REACTION PRODUCTS, PASSING SAID COOLED PRODUCTS TO A SEPARATION ZONE TO RECOVER POLYMER CONTAMINANTS FROM THE LOWER PORTION THEREOF, AN INTERMEDIATE FRACTION FREE OF POLYMER CONTAMINANTS, AND A PURIFIED ALKYLATABLE HYDROCARBON FROM THE UPPER PORTION, COOLING SAID INTERMEDIATE FRACTION, PASSING SAID COOLED FRACTION TO SAID CONVERSION ZONE TO CONTROL THE TEMPERATURE THEREOF WITHIN THE DESIRED LIMITS AND PASSING SAID PURIFIED ALKYLATABLE HYDROCARBON TO AN ALKYLATION PROCESS.
