Claim 1
Independent Claim
100 words
A PROCESS WHICH COMPRISES REGENERATING A MOLYBDENUM OXIDE CATALYST CONTAINING CARBONACEOUS MATERIAL BY BURNING WITH AN OXYGEN CONTAINING GAS FOR THE REMOVAL OF CARBONACEOUS MATERIAL IN AN AMOUNT SUFFICIENT TO RESTORE CATALYTIC PROPERTIES SUBSTANTIALLY FOR REFORMING LIGHT HYDROCARBON OILS, TREATING THE REGENERATED CATALYST WITH A GASEOUS MATERIAL CONTAINING FREE HYDROGEN AT A TEMPERATURE OF ABOUT 875* TO ABOUT 1050* F., IN THE PRESENCE OF ADDED WATER IN THE AMOUNT OF ABOUT 0.1 TO ABOUT 15 MOL PERCENT, CONTACTING THE TREATED CATALYST WITH A LIGHT HYDROCARBON OIL UNDER SUITABLE REFORMING CONDITIONS TO PRODUCE A REFORMED LIQUID PRODUCT OF HIGH ANTI-KNOCK QUALITY.
