Method of using a single reactor for a plurality of conversions

Claim 1

A PROCESS FOR CATALYTICALLY CRACKING AND DESULFURIZING A HYDROCARBON MIXTURE IN A SINGLE MULTI-ZONE REACTOR WHICH COMPRISES INTRODUCING HOT ACTIVE PARTICLE FORM SOLID CATALYST WHICH COMBINES ACTIVITY FOR CONVERTING HYDROCARBONS BOILING ABOVE THE GASOLINE RANGE INTO HYDROCARBONS BOILING IN THE GASOLINE RANGE WITH ACTIVITY FOR HYDROGENATING ORGANICALLY COMBINED SULFUR IN SAID HYDROCARBON MIXTURE TO HYDROGEN SULFIDE AT A TEMPERATURE OF ABOUT 975*F. TO ABOUT 1075*F. INTO A MULTI-ZONE REACTOR, FLOWING A PORTION OF SAID CATALYST THROUGH A BY-PASS ZONE, FLOWING THE BALANCE OF SAID CATALYST THROUGH A DESULFURIZING ZONE, FLOWING A STREAM OF CATALYST FROM SAID BY-PASS ZONE, FLOWING A STREAM OF CATALYST FROM SAID DESULFURIZING ZONE, COMBINING SAID FLOWING STREAMS OF CATALYST, INTRODUCING SAID COMBINED FLOWING STREAMS OF CATALYST INTO A CATALYST CRACKING ZONE, INTRODUCING HYDROCARBON MIXTURE TO BE DESULFURIZED AND CATALYTICALLY CRACKED INTO SAID DESULFURIZING ZONE AT A TEMPERATURE OF ABOUT 650*F. TO 850*F., FLOWING SAID HYDROCARBON MIXTURE AT A LIQUID SPACE VELOCITY OF ABOUT 0.25 TO 1.0 V./V./HR. THROUGH SAID DESULFURIZING ZONE IN CONTACT WITH SAID CATALYST TO PRODUCT AN AT LEAST PARTIALLY DESULFURIZED HYDROCARBON MIXTURE AND TO LAY DOWN A CARBONACEOUS DEPOSITE ON SAID CATALYST, FLOWING SAID AT LEAST PARTIALLY DE-
