A PROCESS FOR REFORMING A LIGHT HYDROCARBON OIL WHICH COMPRISES PASSING SAID OIL AT A TEMPERATURE BELOW THE POINT OF SUBSTANTIAL THERMAL CRACKING TO A HEATED ZONE CONTAINING A FIXED BED OF PLATINUM REFORMING CATALYST, CONTACTING SAID OIL WITH CATALYST UNDER SUITABLE REFORMING CONDITIONS AND SUPPLYING HEAT TO THE CATALYST DURING SAID CONTACT OF THE OIL WITH THE CATALYST SUCH THAT THE AVERAGE TEMPERATURE IN THE REMAINING PORTION OF THE BED IS BETWEEN ABOUT 700*F. AND ABOUT 900*F. AND THE AVERAGE TEMPERATURE IN THE REMAINING PORTION OF THE CATALYST BED IS BETWEEN ABOUT 20*F*. AND ABOUT 150*F. GREATER THAN THE TEMPERATURE IN SAID INITIAL PORTION WHEREBY THE TEMPERATURE OF THE RESULTANT PRODUCT IS GREATER THAN THE INLET TEMPERATURE OF THE OIL BEING FED TO SAID HEATED ZONE AND PRODUCING A REFORMED PRODUCT HAVING AN OCTANE NUMBER OF AT LEAST ABOUT 60.
