Hydroformer regenerator temperature control

Claim 1

A METHOD FOR CONTROLLING THE TEMPERATURE OF A POWDERED CATALYTIC MATERIAL UNDERGOING REGENERATION IN A REGENERATION ZONE IN THE FORM OF A DENSE FLUIDIZED BED OF SAID POWDERED CATALYTIC MATERIAL WHICH COMPRISES CONTACTING THE FLUIDIZED BED WITH COOLING TUBES IN THE SAID REGENERATION ZONE IN SUCH A MANNER THAT THE SAID COOLING TUBES ARE PARTIALLY SUBMERGED IN THE SAID DENSE FLUIDIZED BED OF CATALYST, PROVIDING A SECOND FLUIDIZED BED OF SAID CATALYTIC MATERIAL IN A SECOND SEPARATE ZONE, WHICH LAST NAMED ZONE IS AT A PRESSURE AND IS IN COMMUNICATION WITH SAID FIRST NAMED ZONE AND CAUSING THE POWDERED CATALYTIC MATERIAL TO FLOW FROM THE REGENERATION ZONE TO THE SAID SECOND NAMED ZONE THROUGH A U-SHAPED CONDUIT AND MAINTAINING A GAS SEAL BETWEEN SAID ZONES WHILE CONTROLLING THE RATE OF FLOW THEREBETWEEN WITHOUT THE USE OF MECHANICALLY CONTROLLED VALVES BY CAUSING CATALYST TO FLOW FROM THE REGENERATION ZONE THROUGH A DOWNCOMER LEG OF SAID U-SHAPED CONDUIT, CONTINUING THE PASSAGE OF THE POWDERED CATALYTIC MATERIAL THROUGH THE BASE OF THE SAID U-SHAPED CONDUIT AND UPWARDLY THROUGH A RISER LEG IN COMMUNICATION WITH SAID SECOND NAMED ZONE, DEVELOPING ELECTRICAL ENERGY REPSONSIVE TO THE TEMPERATURE OF THE CATALYST IN THE REGENERATION ZONE, CONTROLLING THE EFFLUX FROM THE REGENERATION ZONE RESPONSIVE TO THE DEVELOPED ELETRIC ENERGY, THEREBY CONTROLLING THE PRESSURE IN THE REGENERATION ZONE, THEREBY CONTROLLING THE LEVEL OF THE FLUID BED OF CATALYST CONTAINED IN THE REGENERATION ZONE BY CONTROLLING THE FLOW OF CATALYST THERETO IN A CONFINED STREAM FROM THE SECOND ZONE, WHEREBY THE IMMERSION OF THE COOLING TUBES IS IN TURN CONTROLLED TO PERMIT THE DESIRED AMOUNT OF COOLING.

Claim 2

A METHOD FOR CONTROLLING THE TEMPERATURE OF A POWDERED CATALYTIC MATERIAL UNDERGOING REGENERATION IN A REGENERATION ZONE IN THE FORM OF A DENSE FLUIDIZED BED OF SAID POWDERED CATALYTIC MATERIAL WHICH COMPRISES CONTACTING THE FLUIDIZED BED WITH COOLING TUBES IN THE SAID REGENERATION ZONE IN SUCH A MANNER THAT THE SAID COOLING TUBES ARE PARTIALLY SUBMERGED IN THE SAID DENSE FLUIDIZED BED OF CATALYST, PROVIDING A SECOND FLUIDIZED BED OF SAID CATALYTIC MATERIAL IN A SECOND SEPARATE ZONE, WHICH LAST NAMED ZONE IS AT A PRESSURE AND IS IN COMMUNICATION WITH SAID FIRST NAMED ZONE AND CAUSING THE POWDERED CATALYTIC MATERIAL TO FLOW FROM THE REGENERATION ZONE TO THE SAID SECOND NAMED ZONE THROUGH A U-SHAPED CONDUIT AND MAINTAINING A GAS SEAL BETWEEN SAID ZONES WHILE CONTROLLING THE RATE OF FLOW THEREBETWEEN WITHOUT THE USE OF MECHANICALLY CONTROLLED VALVES BY CAUSING CATALYST TO FLOW FROM THE REGENERATION ZONE THROUGH A DOWNCOMER LEG OF SAID U-SHAPED CONDUIT, CONTINUING THE PASSAGE OF THE POWDERED CATALYTIC MATERIAL THROUGH THE BASE OF THE SAID U-SHAPED CONDUIT AND UPWARDLY THROUGH A RISER LEG IN COMMUNICATION WITH SAID SECOND NAMED ZONE, DEVELOPING ELECTRICAL ENERGY REPSONSIVE TO THE TEMPERATURE OF THE CATALYST IN THE REGENERATION ZONE, CONTROLLING THE EFFLUX FROM THE REGENERATION ZONE RESPONSIVE TO THE DEVELOPED ELETRIC ENERGY, THEREBY CONTROLLING THE PRESSURE IN THE REGENERATION ZONE, THEREBY CONTROLLING THE LEVEL OF THE FLUID BED OF CATALYST CONTAINED IN THE REGENERATION ZONE BY CONTROLLING THE FLOW OF CATALYST THERETO IN A CONFINED STREAM FROM THE SECOND ZONE, WHEREBY THE IMMERSION OF THE COOLING TUBES IS IN TURN CONTROLLED TO PERMIT THE DESIRED AMOUNT OF COOLING.
