Abstract
PROCEDE DE REGENERATION D'UNE MATIERE ADSORBANTE SE PRESENTANT SOUS FORME DE PARTICULES CHARGEES D'AU MOINS DEUX COMPOSES VOLATILS DE STABILITES THERMIQUES DIFFERENTES. ON PROVOQUE UNE CALCINATION DE L'UN DES COMPOSES VOLATILS DANS UNE PREMIERE COLONNE DE CONTACT, DANS LAQUELLE LA MATIERE EST ENTRAINEE ET MISE EN SUSPENSION PAR UN COURANT DE GAZ OXYDANT, EN Y ETANT PORTEE A UNE TEMPERATURE SUFFISAMMENT ELEVEE, ET LES PRODUITS GAZEUX DESORBES DANS CETTE PREMIERE COLONNE SONT READSORBES PAR REFROIDISSEMENT DANS UNE SECONDE COLONNE DE CONTACT. PRINCIPALES APPLICATIONS: REGENERATION DES PARTICULES D'ALUMINE AYANT ABSORBE DES GOUDRONS ET DES COMPOSES FLUORES.
