Regenerator temperature control

Claim 1

THE METHOD OF CONTROLLING THE TEMPERATURE OF A POWDERED CATALYST WHICH IS CIRCULATED CONTINUOUSLY BETWEEN A HYDROFORMING REACTION ZONE AND AN OXIDATIVE REGENERATION ZONE WHICH COMPRISES CONTINUOUSLY SUPPLYING HYDROFORMING CATALYST PARTICLES CONTAINING CARBONACEOUS DEPOSITS TO A DENSE FLUIDIZED BED OF CATALYST SUPERIMPOSED BY A DILUTE PHASE IN THE REGENERATION ZONE, DISPOSING A COOLING MEANS IN SAID REGENARATION ZONE, WHICH COOLING MEANS IS AT LEAST PARTIALLY SUBMERGED IN THE SAID DENSE FLUIDIZED BED OF CATALYST, TREATING THE CATALYST IN THE REGENERATION ZONE WITH AN OXYGEN-CONTAINING GAS TO BURN CARBONACEOUS DEPOSITS THEREFROM, PROVIDING A DENSE, FLUIDIZED BED OF POWDERED CATALYST OF THE SAME COMPOSITION AS THAT IN THE HYDROFORMING REACTION AONE-REGENERATION ZONE CIRCULATION SYSTEM IN A THIRD ZONE WHICH THIRD ZONE IS OF SUBSTANTIALLY SMALLER SIZE THAN SAID REGENERATION ZONE WHICH THIRD ZONE IS IN COMMUNICATION WITH THE SAID REGENERATION ZONE, AND VARYING THE DEGREE FO SUBMERGENCE OF THE COOLING MEANS IN THE DENSE FLUIDIZED BED OF CATALYST IN THE REGENERATION ZONE RESPONSIVE TO TEMPERATURE CONDITIONS PREVAILING IN SAID BED BY CAUSING CATALYST TO FLOW BETWEEN THE REGENERATION ZONE AND THE SAID THIRD ZONE, THEREBY VARYING THE AMOUNT OF HEAT REMOVVED FROM THE CATALYST UNDERGOING REGENERATION THUS CONTROLLING THE TEMPERATURE OF THE CATALYST IN SAID TEFENERATION ZONE AND MAINTAING THE CIRCULATION RATE OF RRTENERATED CATALYST FROM THE REGENERATOR TO THE REACTOR AT A SUBSTANTIALLY CONSTANT VALUE.

Claim 2

THE METHOD OF CONTROLLING THE TEMPERATURE OF A POWDERED CATALYST WHICH IS CIRCULATED CONTINUOUSLY BETWEEN A HYDROFORMING REACTION ZONE AND AN OXIDATIVE REGENERATION ZONE WHICH COMPRISES CONTINUOUSLY SUPPLYING HYDROFORMING CATALYST PARTICLES CONTAINING CARBONACEOUS DEPOSITS TO A DENSE FLUIDIZED BED OF CATALYST SUPERIMPOSED BY A DILUTE PHASE IN THE REGENERATION ZONE, DISPOSING A COOLING MEANS IN SAID REGENARATION ZONE, WHICH COOLING MEANS IS AT LEAST PARTIALLY SUBMERGED IN THE SAID DENSE FLUIDIZED BED OF CATALYST, TREATING THE CATALYST IN THE REGENERATION ZONE WITH AN OXYGEN-CONTAINING GAS TO BURN CARBONACEOUS DEPOSITS THEREFROM, PROVIDING A DENSE, FLUIDIZED BED OF POWDERED CATALYST OF THE SAME COMPOSITION AS THAT IN THE HYDROFORMING REACTION AONE-REGENERATION ZONE CIRCULATION SYSTEM IN A THIRD ZONE WHICH THIRD ZONE IS OF SUBSTANTIALLY SMALLER SIZE THAN SAID REGENERATION ZONE WHICH THIRD ZONE IS IN COMMUNICATION WITH THE SAID REGENERATION ZONE, AND VARYING THE DEGREE FO SUBMERGENCE OF THE COOLING MEANS IN THE DENSE FLUIDIZED BED OF CATALYST IN THE REGENERATION ZONE RESPONSIVE TO TEMPERATURE CONDITIONS PREVAILING IN SAID BED BY CAUSING CATALYST TO FLOW BETWEEN THE REGENERATION ZONE AND THE SAID THIRD ZONE, THEREBY VARYING THE AMOUNT OF HEAT REMOVVED FROM THE CATALYST UNDERGOING REGENERATION THUS CONTROLLING THE TEMPERATURE OF THE CATALYST IN SAID TEFENERATION ZONE AND MAINTAING THE CIRCULATION RATE OF RRTENERATED CATALYST FROM THE REGENERATOR TO THE REACTOR AT A SUBSTANTIALLY CONSTANT VALUE.
