Fluidized catalyst regeneration

Claim 1

IN A PROCESS FOR THE CATALYTIC CONVERSION OF HYDROCARBONS WHEREIN SAID HYDROCARBONS, IN GASEOUS FORM, ARE INTIMATELY CONTACTED WITH A FLUIDIZED PARTICULATE SOLID HYDROCARBON CONVERSION CATALYST IN A REACTION ZONE, AND DURING SAID CONTACT THE CATALYST BECOMES COATED WITH CARBONACEOUS DEPOSITS AND WHEREIN THE ACTIVITY OF SAID CATALYST IS MAINTAINED BY WITHDRAWING CATALYST FROM SAID REACTION ZONE ANDCYCLINGSAID CATALYST TO A REGENERATION ZONE IN WHICH THE CATALYST IS CONTACTED WIT HAN OXYGENCONTAINING GAS UNDER COMBUSTION CONDITIONS TO REMOVE SAID DEPOSITS, THE IMPROVEMENT WHEREBY THE RATE OFCOMBUSTION OF SAID CARBONACEOUS DEPOSITS IS INCREASED WHICH COMPRISES MAINTAINING IN SAID REGENERATION ZONE HIGH ENERGY IONIZING RADIATION OF AN INTENSITY SUFFICIENT TO INCREASE THE COMBUSTION RATE OF SAID CARBONACEOUS DEPOSITS, SAID INTENSITY BEING EFFECTIVE TO PROVIDE A DOSAGE OF AT LEAST ABOUT 10,000 ROENTGENS PER HOUR THROUGHOUT A MAJOR PORTION OF SAID ZONE.
