Abstract

L'INVENTION A POUR OBJET UN PROCEDE DE FABRICATION DE CATALYSEUR ACTIVE PAR CERIUM. ELLE EST CARACTERISEE EN CE QU'ON INTRODUIT UNE POUDRE CONTENANT: DE LA MAGNETITE DE L'OXYDE D'ALUMINIUM, DE L'HYDROXYDE DE POTASSIUM, DE L'OXYDE DE CALCIUM, DE L'OXYDE DE MAGNESIUM ET DE LA SILICE, DANS UN MELANGEUR, AVEC UNE SOLUTION DE NITRATE DE CERIUM, AFIN D'OBTENIR UNE CONCENTRATION EN CERIUM METALLIQUE DE 0,5 A 2,5 EN POIDS DANS LE CATALYSEUR FINAL, ON EFFECTUE LA GRANULATION DE LA POUDRE AINSI TRAITEE DANS UN GRANULATEUR A PLATEAU EN VUE D'OBTENIR IMMEDIATEMENT DE PETITS GRANULES SPHERIQUES QUI GROSSISSENT RAPIDEMENT SOUS LA FORME DE SPHERES FACILES A MANUTENTIONNER ET NON FRAGILES PAR ABSORPTION CONTINUE DE LA POUDRE INTRODUIRE DANS L'APPAREIL, EN CE QU'ON EFFECTUE ENSUITE D'ABORD UN SECHAGE DES SPHERES DE CATALYSEUR A UNE TEMPERATURE COMPRISE ENTRE 100 ET 200C DANS UN FOUR PUIS, FINALEMENT, UN FRITTAGE DES SPHERES DANS UNE ATMOSPHERE D'ARGON A UNE TEMPERATURE DE L'ORDRE DE 1250 A 1350C. ELLE SE RAPPORTE A LA SYNTHESE D'AMMONIAC.
