Claim 1

IMPROVED PROCESS FOR THE CONVERSION OF RELATIVELY HIGH BOILING HYDROCARBON CONSTITUENTS INTO RELATIVELY LOW BOILING CONSTITUENTS WHICH COMPRISES, CONTACTING A HYDROCARBON FEED STREAM IN A REACTION ZONE IN THE PRESENCE OF FLUIDIZED CATALYTIC PARTICLES UNDER TEMPERATURE AND PRESSURE CONDITIONS ADAPTED TO CRACK SAID HIGH BOILING HYDROCARBON CONSTITUENTS, WITHDRAWING CATALYTIC PARTICLES FROM SAID REACTION ZONE AND REGENERATING THE SAME IN A FLUIDIZED CATALYTIC REGENERATION ZONE, WITHDRAWING REGENERATED PARTICLES FROM SAID REGENERATION ZONE AND RECYCLING A PORTION OF THE SAME TO SAID REACTION ZONE, COMBINING A PORTION OF SAID WITHDRAWN CATALYTIC PARTICLES FROM SAID REGENERATION ZONE WITH A SECOND HYDROCARBON FEED STREAM, PASSING SAID SECOND HYDROCARBON STREAM TO TO A SUSPENSOID CRACKING ZONE MAINTAINED UNDER TEMPERATURE AND PRESSURE CONDITIONS ADAPTED TO SECURE THE DESIRED CONVERSION OF THE OIL, WITHDRAWING A CRACKED PRODUCT OVERHEAD FROM SAID REACTION ZONE, WITHDRAWING A CRACKED PRODUCT FROM SAID SUSPENSOID ZONE AND INTRODUCING THE SAME THROUGH PRESSURE REDUCING MEANS TO THE DILUTE PHASE ZONE ABOVE SAID REACTION ZONE WHEREBY SAID CRACKED PRODUCTS FROM SAID SUSPENSOID CRACKING ZONE PASS THROUGH SEPARATION MEANS IN THE TOP OF SAID REACTION ZONE AND WHEREIN THE CATALYTIC PARTICLES ARE SEPARATED FROM SAID CRACKED PRODUCTS.
