A PROCESS WHICH COMPRISES PASSING AN INERT GAS OVER A REFORMING CATALYST IN A CONTACT ZONE, MAINTINING THE TEMPERATURE OF THE CATALYST AT A LEVEL WHERE THE PREDOMINANT REACTION WHICH CAN TAKE PLACE IS DEHYDROGENATION, PASSING A LIGHT HYDROCARBON OIL CONTAINING NAPHTHENES IN CONTACT WITH SAID CATALYST WHILE CONTINUING THE FLOW OF INERT GAS, THEREBY EFFECTING THE DEHYDROGENATION OF THE NAPHTHENS TO PRODUCE HYDROGEN, WITHDRAWING FROM SAID CONTACTING ZONE GASEOUS MATERIAL CONTAINING HYDROGEN AND INERT GAS, CONTINUING TO INTRODUCE INERT GAS INTO SAID CONTACTING ZONE UNTIL SUCH TIME THAT THE HYDROGEN CONCENTRATION OF THE GASEOUS EFFLUENT IS SUFFICIENTLY HIGH FOR USE IN A REFORMING OPERATION, THEREAFTER SUNSTANTIALLY DECREASING THE FLOW OF INERT GAS INTO SAID CONTACTING ZONE AND DURING THE ABOVE OPERATION ADJUSTING THE PRESSURE AND TEMPERATURE CONDITIONS FOR A REFORMING OPERATION TO PRODUCE A HIGHER OCTANE PRODUCT THAN IN THE PREDOMINANTLY DEHYDROGENATION REACTION.
