Abstract

APPARATUS FOR TRANSFERRING PARTICULATE CONTACT MATERIAL BY GRAVITY FLOW FROM AN UPPER CONTACT ZONE (28) WHERE IT IS CONTACTED BY A FIRST GAS STREAM FLOWING RADIALLY, TO A LOWER TREATMENT ZONE (66) WHERE IT IS CONTACTED BY A SECOND GAS STREAM FLOWING UPWARDLY INCLUDES A GENERALLY ANNULAR PARTICLE-CONTAINING TRANSITION ZONE (44) WHICH CONNECTS THE UPPER AND LOWER ZONES. THE TRANSITION ZONE HAS A VERTICAL HEIGHT H WHICH EFFECTIVELY PREVENTS THE SECOND GAS STREAM FROM CONTACTING THE PARTICULATE MATERIAL IN THE UPPER ZONE (28). IN A PREFERRED EMBODIMENT IN THE FORM OF A CATALYST REGENERATOR, CATALYST PARTICLES CAN BE SAMPLED (84) FOR CARBON LEVEL IN THE TRANSITION ZONE (44) TO DETERMINE IF THE CARBON BURN-OFF THEREFROM IS SUFFICIENTLY COMPLETE IN AN UPPER RADIAL FLOW REGENERATOR BED BY CONTACT WITH A FIRST GAS STREAM, HAVING A RELATIVELY LOW OXYGEN LEVEL. THE SAMPLING CAN BE DONE ON STREAM, EVEN THOUGH A SECOND GAS STREAM, SUCH AS RELATIVELY OXYGEN-RICH HALOGENATION GAS, IS PASSING UP THROUGH THE CATALYST IN THE LOWER ZONE (66).(FIG 1)
