Abstract

A.LE PROCEDE EST DESTINE A EPURER UN CHARBON ACTIF QUI A ADSORBE DU SOUFRE, OU QUI EN CONTIENT. B.ON TRAITE LE CHARBON ACTIF, EN PRESENCE D'OXYGENE, AVEC DE L'EAU A UNE TEMPERATURE ENTRE LA TEMPERATURE AMBIANTE ET CELLE D'EBULLITION DE LA SUSPENSION A UN PH SUPERIEUR A 7. C.CE PROCEDE PERMET DE RECUPERER LE CHARBON ACTIF QUI A ADSORBE DU SOUFRE OU D'UTILISER DES MATIERES PEU COUTEUSES MAIS CONTENANT DU SOUFRE POUR LA PREPARATION DE CHARBON ACTIF.A. THE PROCESS IS INTENDED TO REMOVE AN ACTIVE CARBON WHICH HAS ADSORBES SULFUR, OR WHICH CONTAINS SULFUR. B. THE ACTIVE CARBON IS TREATED, IN THE PRESENCE OF OXYGEN, WITH WATER AT A TEMPERATURE BETWEEN THE AMBIENT TEMPERATURE AND THE BOILING TEMPERATURE OF THE SUSPENSION AT A PH HIGHER THAN 7. C. THIS PROCESS MAKES THE COAL RECOVERY ACTIVE WHICH HAS ADSORBES SULFUR OR TO USE LOW COST MATERIALS BUT CONTAINING SULFUR FOR THE PREPARATION OF ACTIVE CARBON.
