Process for manufacturing zinc and cadmium acetate-activated carbon catalysts

Claim 1

PROCESS FOR PRODUCING A CATALYST CONSISTING OF ACTIVATED CARBON IMPRENATED WITH A SUBSTANCE SELECTED FROM THE GROUP CONSISTING O ZINC ACETATE AND CADMIUM ACETATE, FOR USE IN THE CATALYTIC PRODUCTION OF MONOMERIC VINYL ESTERS IN THE GAS PHASE, WHICH COMPRISES PLACING SAID ACTIVATED CARBON IN A POSITION OF REST IN A SOLUTION OF SAID SUBSTANCE EXCEEDING IN VOLUME THE QUANTITY REQUIRED TO IMPREGNATE SAID ACTIVATED CARBON, KEEPING TRACK OF THE REDUCTION OF CONCENTRATION OF SAID SOLUTION DURING THE IMPREGNATION OF SAID ACTIVATED CARBON, REMOVING THE IMPREGNATED ACTIVATED CARBON FROM THE EXCESS SOLUTION BEFORE THE CONCLUSION OF THE ADSORPTION PROCESS, AND DRYING SAID IMPREGNATED ACTIVATED CARBON, SAID PROCESS BEING CHARACTERIZED BY THE FACT THAT THE IMPREGNATED ACTIVATED CARBON IS REMOVED FROM THE EXCESS IMPREGNATING SOLUTION AS SOON AS SAID SOLUTION HAS REACHED THE CONCENTRATION K''=(CK-BA)/(C-BE) WHERE "A" IS G. OF A MEMBER SELECTED FROM THE GROUP CONSISTING OF ZN/KG. AND CD/KG. OF ACTIVATED CARBON, "B" IS THE QUANTITY OF ACTIVATED CARBON PER CHARGE IN KG., "C" IS THE QUANTITY OF IMPREGNATING SOLUTION IN LITERS, "E" IS THE ABSORPTIVITY OF THE ACTIVATED CARBON IN LITERS/KG. "K" IS THE INITIAL CONCENTRATION IN G. OF A MEMBER SELECTED FROM THE GROUP CONSISTING OF ZN AND CD/LITERS OF SOLUTION, AND "K" IS THE FINAL CONCENTRATION IN G. OF A MEMBER SELECTED FROM THE GROUP CONSISTING OF ZN AND CD/LITERS OF SOLUTION.
