Fluidization process

Claim 1

A PROCESS FOR ADJUSTING AND CONTROLLING THE SOLIDS AND HEAT CONTENTS OF AN EXPANDED FLUIDIZED REACTING BED WHICH COMPRISES PERIODICALLY ESTABLISHING AND MAINTAINING A TWO-DIRECTIONAL FLOW AND INTERCHANGE OF REACTANT-GAS FLUIDIZED SOLID BED PARTICLES FROM SAID RECTING BED WITH INERT-GAS SUSPENDED PARTICLES OF THE SAME CHEMICAL COMPOSITION FROM A SEPARATELY MAINTAINED AUXILIARY FLUIDIZED NON-REACTING BED, EFFECTING SAID INTERCHANGE THROUGH AN INCLINED RESTRICTED COMMUNICATING PASSAGE MAINTAINED BETWEEN THE UPPER PORTION OF EACH OF SAID FLUIDIZED BEDS, DURING SAID INTERCHANGE MAINTAINING A HIGHER STATIC PRESSURE BY MEANS OF SAID INERT GAS IN SAID AUBILLARY BED OVER THAT PREVAILING IN SAID REACTING BED AND THE LEVEL OF THE EXPANDED REACTING BED ABOVE AN INLET INTO SAID COMMUNICATING PASSAGE, OVERFLOWING SUSPENDED REACTING BED PARTICLES FROM SAID REACTING BED INTO SAID PASSAGE FOR FLOW DOWNWARDLY THERETHROUGH BY GRAVITY ALONG THE BOTTON PORTION OF SAID PASSAGE AND INTO SAID AUXILIARY BED, CONCURENTLY THEREWITH FLOWING INERT-GAS SUSPENDED PARTICLES FROM SAID AUXILIARY BED UPWARDLY THROUGH THE UPPER PORTION OF SAID PASSAGE AND INTO SAID REACTING BED BY MAINTAINING A HIGH UPWARD SUPERFICIAL INERT GAS VELOCITY IN SAID PASSAGE RANGING FROM 5-10 TIMES THE GAS VELOCITY MAINTAINED IN SAID AUXILIARY BED, AND CONTINUING SAID PARTICLE INTERCHANGE BETWEEN SAID AUXILIARY AND REACTING BEDS UNTIL THE DESIRED ADJUSTMENT BEING MADE IN SAID REACTING BED BECOMES EFFECTED.
