Abstract: 1. IN A REGENERATOR FOR A FLUIDIZED CATALYST WHEREIN THE PARTICULATED CATALYST MATERIAL IS CIRCULATED WITHIN A REGENERATION COMPARTMENT HAVING VERTICAL WALLS, IN A TURBULENT FLOW BY A CARRIER GAS TO FORM A FLUIDIZED BED, AND WHEREIN THE CONDITION OF SAID FLUIDIZED BED IS REGULATED TO MAINTAIN PREDETERMINED OPERATING CONDITIONS THEREIN, THE IMPROVEMENT FOR CONTINUOUSLY MONITORING THE PRESSURE WITHIN SAID FLUIDIZED BED COMPRISING, A CONDUIT EXTENDING INTO SAID REGENERATOR COMPARTMENT AND HAVING AN OPEN END DISPOSED IN SAID FLUIDIZED CATALYST BED, THE OTHER END OF SAID CONDUIT COMMUNICATED WITH A SOURCE OF A PURGE GAS, A PRESSURE SENSING ELEMENT CONNECTED TO SAID CONDUIT, AND IN COMMUNICATION WITH SAID REGENERATION COMPARTMENT, A SHEILD DISPOSED ABOUT SAID CONDUIT OPEN END DEFINING A CHAMBER IN COMMUNICATION WITH SAID FLUIDIZED BED WHEREBY TO RECEIVE THE FLUIDIZED CATALYST AS WELL AS PURGE GAS AT THE CONDUIT OPEN END, SAID SHEILD INCLUDING A CYLINDRICAL ELEMENT HAVING A PERFORATED WALL SPACED FROM SAID CONDUIT OPEN, END, THEREBY DEFINING AN ANNULUS ABOUT THE CONDUIT, AND A SUBSTANTIALLY FLAT PERFORATED FACE PLATE AT THE END OF SAID CYLINDRICAL SHEILD ELEMENT TO DEFINE A PARTIAL CLOSURE TO THE LATTER ADJACENT TO SAID CONDUIT OPEN END, SAID FACE PLATE BEING DISPOSED IN A PLANE SUBSTANTIALLY PARALLEL TO THE VERTICAL WALLS OF SAID REGENERATION COMPARTMENT.

Abstract: APPARATUS FOR EFFECTING REGENERATION OF CATALYST MATERIAL IN A FLUID CATALYTIC CRACKING PROCESS. IN THE LATTER MENTIONED PROCESS, A HYDROCARBON MATERIAL IS CONTACTED WITH FLUIDIZED SOLID CATALYST WITHIN A REACTION ZONE WHEREBY TO EFFECT CONVERSION OF AT LEAST A PORTION OF SAID HYDROCARBON MATERIAL TO A DESIRED CONVERSION PRODUCT, SIMULTANEOUSLY, THE CATALYST IS AFFECTED BY THE DEPOSITION OF A LAYER OF COKE ON OR ABOUT THE OUTER SURFACE THEREOF. THE INVENTION RELATS SPECIFICALLY TO AN APPARATUS FOR REGENERATING THE FLUIDIZED CATALYST FOR REUSE, WHEREIN PARTICLES OF THE LATTER ARE TRANSPORTED THROUGH AN ELONGATED REACTION FLOW PATH. THE REACTION ACHIEVED IN THE REGENERATING CHAMBER CAUSES THE COKE TO BE BURNED FROM THE CATALYST IN A COMBUSTION SUPPORTING ATMOSPHERE PROVIDED BY A UNIFORM AIR FLOW INTRODUCED AT THE CHAMBER LOWER END IN A MANNER TO AVOID FLOW DISCONTINUITIES AND DISTURBANCES TO THE DESIRED AIR STREAM.
