Abstract

A.PROCEDE POUR PRODUIRE DES CATALYSEURS DE DENITRATION EN FORME DE PLAQUES. B.CE PROCEDE CONSISTE A PREPARER UNE BOUILLIE D'OXYDE DE TITANE HYDRATE ET D'UN SOL CHOISI DANS LE GROUPE COMPRENANT LES SOLS DE SILICE, D'ALUMINE ET D'OXYDE DE TITANE, A CUIRE LA BOUILLIE POUR OBTENIR UNE MATIERE POREUSE, A PULVERISER CETTE MATIERE POREUSE, A FIXER CETTE MATIERE POREUSE SUR UNE GRILLE METALLIQUE A L'AIDE D'UN LIANT POUR PRODUIRE UNE PIECE EN FORME DE PLAQUE, A SECHER OU A CUIRE CETTE PIECE POUR OBTENIR UN SUPPORT POREUX ET A DEPOSER UN COMPOSANT A ACTIVITE CATALYTIQUE SUR CE SUPPORT. C.CONCERNE L'EPURATION DES GAZ D'ECHAPPEMENT ET DES FUMEES INDUSTRIELLES.A.PROCEDE TO PRODUCE PLATE-SHAPED DENITRATION CATALYSTS. B. THIS PROCESS CONSISTS OF PREPARING A SLURRY OF HYDRATED TITANIUM OXIDE AND A SOIL CHOSEN FROM THE GROUP INCLUDING THE SOILS OF SILICA, ALUMINA AND TITANIUM OXIDE, BAKING THE BOIL TO OBTAIN A POROUS MATERIAL, TO SPRAY THIS POROUS MATERIAL, TO FIX THIS POROUS MATERIAL ON A METAL GRID USING A BINDER TO PRODUCE A PLATE-SHAPED PART, TO DRY OR BAKE THIS PART TO OBTAIN A POROUS SUPPORT AND TO DEPOSIT A COMPONENT A CATALYTIC ACTIVITY ON THIS MEDIA. C. CONCERNS THE PURIFICATION OF EXHAUST GASES AND INDUSTRIAL FUMES.
