Claims

1. A CONTINUOUS METHOD FOR PURIFYING AN ACIDIC GASCONTDAINING STREAM WHICH COMPRISES PASSING SAID ACIDIC GAS-CONTAINING STREAM INTO THE LOWER PORTION OF A CONTACTING ZONE CONTAINING DRY, SUBDIVIDED SOLID PARTICLFES COMPRISING AN ADSORPTIVE SOLID AND AN ALIPHATIC AMINE AT A VELOCITY SUFFICIENT TO MAINTAIN SAID SOLID IN A FLUIDIZED BED, CONTACTING SAID STREAM WITDH SAID PARTICLES AT AN ACIDIC GAS ABSORBING TEMPERATURE NOT IN EXCESS TO 300* F., SSEPARATING A RESULTANT PURIFIED GAS STREAM FROM SAID FLUIDIZED BED, PASSING SAID PURIFIED STREAM FROM SAID CONTACTING ZONE, PASSING AT LEAST A PORTION OF THE SOLID PARTICLES FROM SAID CONTACTING ZONE INTOK A REGENERATION ZONE AND THEREIN REGENERATING THE SAME BY CONTACT WITH A REDUCING GAS AT A REGENERATING TEMPARATURE NOT IN EXCESS OF 300* F. AND RDETURNING REGENERATED PARTICLES TO SAID CONTACTING ZONE
