Process of regenerating granular ma- terials impregnated with active com- ponents in a cyclic process of produc- ing chlorine

Claim 1

IN A CYCLIC PROCESS OF PRODUCING CHLORINE FROM A MATERIAL SELECTED FROM THE GROUP CONSISTING OF HYDROGEN CHLORIDE AND AMMONIUM CHLORIDE, WHEREIN A GRAVITY-FLOW MOVING BED OF GRANULAR MATERIALS IS PASSED THROUGH SUPERIMPOSED CHLORIDATION AND OXIDATION ZONES IN WHICH THE REACTING MASSES MOVING DOWNWARDLY THRETHROUGH MEET COUNTERCURRENTS OF HYDROGEN CHLORIDE AND OF A MOLECULAR OXYGEN-CONTAINING GAS RESPECTIVELY, WHILE MAINTAINING THE CHLORIDIZING ZONE AT A TEMPERATURE OF ABOUT 350-500* C. AND THE OXIDATION ZONE AT A TEMPERATURE OF ABOUT 500-600*C., SAID GRANULAR MATERIALS COMPRISING SOLID GRANULAR SUPPORTS IMPREGNATED WITH ACTIVE COMPONENTS WHICH ARE SELECTED FROM THE GROUP CONSISTING OF COMPOUNDS OF K, FE AND CU, AND WHEREIN DURING SAID PROCESS THERE IS A DECREASE IN THE CONCENTRATION OF ACTIVE COMPONENTS ON SAID GRANULAR SUPPORTS, THE IMPROVEMENT WHICH COMPRISES INJECTING PARTICULATES OF SAID ACTIVECOMPONENTS INTO SAID MOVING BED AT A ZONE IN THE PROCESS WHERE THE ACTIVE COMPONENTS WHICH IMPREGNATE THE SUPPORTS ARE SUBSTANTIALLY IN A STICKY CONDITION, SO THAT THE INJECTED PARTICULATES OF ACTIVE COMPONENTS ADHERE TO THE GRANULAR MATERIALS OF THE MOVING BED.
