A HYDROFORMING PROCESS FOR THE PRODUCTION OF A PETROLEUM PRODUCT HAVING AN OCTANE NUMBER (RESEARCH) CLEAR OF AT LEAST 100 FROM A PETROLEUM HYDROCARBON OF LOW OCTANE NUMBER, COMPRISING: CONTACTING A PETROLEUM FEEDSTOCK HAVING A FINAL BOILINBG POINT OF NOT MORE THAN 400*F. WITH AT LEAST ONE FIXED BED OF A PLATINUM REFORMING CATALYST UNDER CONDITIONS INCLUDING A TEMPERATURE WITHIN THE RANGE OF ABOUT900* TO 957*F., A PRESSURE WITHIN THE RANGE OF ABOUT 300 TO 500P.S.I.G., A SPACE VELOCITY WITH IN THE RANGE OF ABOUT 0.5 TO 2.00 V./V./HR., AND A MOLAR HYDROGEN TO HYDROCARBON RATIO WITHIN THE RANGE OF ABOUT 6-12:1, TO GIVE A PRODUCT HAVING AN OCTANE NUMBER (RESEARCH) CLEAR OF 85 TO 95, SUCH THAT THE CATALYST LIFE IS AT LEAST 40 BARRELS OF SAID FEEDSTOCK PER POUND OF CATALYST, AND CONTACTING SAID PRODUCT IN A SECOND STAGE WITH A HALOGEN-FREE PLATINUM REFORMING CATALYST IN AN AMOUNT WHICH IS FORM 25 TO 75% VOL. OF THE AMOUNT USED IN THE FIRST STAGE, UNDER CONDITIONS INCLUDING A TEMPERATURE WITHIN THE RANGE OF ABOUT 975 TO 1025*F., A PRESSURE WITHIN THE RANGE OF ABOUT 300 TO 500 P.S.I.G., AND A MOLAR HYGROGEN TO HYDROCARBON RATIO WITHIN THE RANGE OF ABOUT 6-12:1, SUCH THAT REGENARATION OF SAID HALOGEN-FREE CATALYST IN SAID SECOND STAGE IS REQUIRED TO GIVE A FINAL PRODUCT HAVING AN OCTANE NUMBER (RESEARCH) CLEAR, OF AT LEAST 100.
