Method for regeneration of moving catalysts

Claim 1

THE PROCESS FOR REGENERATION OF SPENT PARTICLE FORM ADSORBENT CONTACT MATERIAL BEARING A CARBONACEOUS CONTMINANT DEPOSIT WHICH COMPRISES, PASSING SAID ADSORBENT DOWNWARDLY THROUGH A CONFINED REGENERATION ZONE AS A SUBSTANTIALLY COMPACT COLUMN OF PARTICLES, BAFFLING THE FLOW OF THE ADSORBENT IS SAID COLUMN TO PROVIDE A PLURALITY OF SPACED APART GAS HANDLING SPACES IN SAID COLUMN WITHIN SAID REGENERATION ZONE, INTRODUCING AN OXYGEN CONTAINING GAS INTO SOME OF SAID GAS SPACES FROM A SOURCE OUTSIDE OF SAID ZONE AND DISTRIBUTING THE GAS FROM SAID GAS SPACES INTO SAID COLUMN TO CONTACT SAID ADSORBENT AND TO EFFECT BURNING OF SAID CARBONACEOUS CONTAMINANT, WITHDRAWING REGENERATION GASES FORMED DURING THE BURNING FROM THE REMAINING GAS SPACES IN SAID COLUMN, MAINTAINING THE ADSORBENT IN THE NORMAL ZONE OF FLOW WHICH IS SUBSTANTIALLY OUTSIDE THE SPHERE OF INFLUENCE OF SAID BAFFLING, AT TEMPERATURE LEVELS WHICH ARE BELOW THAT WHICH WILL CAUSE HEAT DAMAGE TO THE ADSORBENT BUT SUFFICIENTLY HIGH TO PROMOTE CONTAMINANT BURNING AT PARACTICAL COMBUSTION RATES, AND AT THE SAME TIME PREVENTING THE ADSORBENT FLOWING NEAR SAID GAS SPACES FROM RISING TO A TEMPERATURE MORE THAN ABOUT 70* F. IN EXCESS OF THOSE IN THE NORMAL ZONE OF FLOW AND FROM RISING TO A HEAT DAMAGING LEVEL BY CONDUCTING SAID FLOW BAFFLING IN A MANNER WHICH WILL LIMIT THE ANGLE OF DIVERGENCE WITH THE VERTICAL OF ADSORBENT FLOW ABOVE SAID GAS SPACES TO NOT GREATER THAN ABOUT 15 DEGREES.
