A PROCESS FOR THE CONVERSION OF PROPENE TO HIGHER BOILING BRANCHED CHAIN HYDROCARBONS WHICH COMPRISES POLYMERIZING THE PROPENE TO A POLYMER HAVING 6 TO 15 CARBON ATOMS PER MOLECULE AND CONTACTING THE POLYMER IN THE PRESENCE OF HYDROGEN AT A TEMPERATURE OF ABOUT 200* TO ABOUT 900*F. AND A PRESSURE OF ABOUT 10 ATMOSPHERES TO ABOUT 100 ATMOSPHERES WITH A SOLID ACIDIC CATALYST SUPPORT ON WHICH IS DEPOSITED A SULFIDE OF A METAL SELECTED FROM THE GROUP CONSISTING OF CHROMIUM, MOLYBDENUM, TUNGSTEN, IRON, COBALT, NICKEL, AND MIXTURES THEREOF, AND RECOVERING A PRODUCT HAVING A HIGH PROPORTION OF C5 TO C6 ISOPARAFFINS.
