CE TRAVAIL CONCERNE L'ETUDE DE SOLUTIONS SOLIDES CEO#2-ZRO#2 COMME SUPPORTS SUSCEPTIBLES DE REMPLACER CEO#2 DANS LA COMPOSITION DES CATALYSEURS TROIS-VOIES. DES CATALYSEURS MODELES RH/CEO#2-ZRO#2 ET RH/CEO#2 ONT ETE PREPARES PAR LA TECHNIQUE D'ECHANGE ANIONIQUE ET NOUS AVONS ETUDIE SUCCESSIVEMENT, LA REDUCTIBILITE, LES INTERACTIONS METAL-SUPPORT, L'ACTIVITE EN REACTION CO-NO-O#2, AINSI QUE LA NATURE ET DE DENOMBREMENT DES SITES ACTIFS DE CES CATALYSEURS. L'AJOUT DE ZIRCONIUM EN SOLUTION SOLIDE DANS L'OXYDE DE CERIUM PERMET D'AMELIORER SA STABILITE THERMIQUE. D'APRES LES ETUDES DE REDUCTION EN TEMPERATURE PROGRAMMEE, LA MOBILITE DES IONS OXYGENE EST PLUS GRANDE DANS LES OXYDES MIXTES QUE DANS LA CERINE, PUISQUE LA REDUCTION DE LEURS COUCHES INTERNES COMMENCE 200C PLUS BAS QUE DANS LE CAS DE CEO#2. LE RHODIUM A UN EFFET PROMOTEUR IMPORTANT SUR LA REDUCTIBILITE DES OXYDES CEO#2-ZRO#2 ET CEO#2 PUISQU'IL PERMET LA REDUCTION TOTALE DE LEUR SURFACE EN-DESSOUS DE 250C, AINSI QUE D'UNE PARTIE DU VOLUME DANS LE CAS DES OXYDES MIXTES. L'ETUDE DES INTERACTIONS METAL-SUPPORT MONTRE QUE LES SUPPORTS CEO#2-ZRO#2 STABILISENT PRATIQUEMENT 100% DU RHODIUM SOUS UNE FORME OXYDEE, MEME APRES TRAITEMENT SOUS HYDROGENE A 500C. CE TYPE DE RHODIUM EST ACCESSIBLE AUX REACTIFS ET FAIT PARTIE D'UN SITE INACTIF EN HYDROGENATION DU BENZENE, MAIS ACTIF EN REACTION CO-NO-O#2. CE SITE EST MIXTE, CONSTITUE D'UN ION RH#X#+, PROBABLEMENT RH#+, A PROXIMITE DE DEUX LACUNES D'OXYGENE DU SUPPORT REDUIT (ASSOCIEES A DES IONS CE#3#+). UNE METHODE DE TITRAGE DE CES SITES EST PRESENTEE. ELLE A L'INTERET D'UTILISER UNE MOLECULE DE LA REACTION CO-NO-O#2 COMME SONDE MOLECULAIRE ET D'ETRE MISE EN UVRE DANS DES CONDITIONS PROCHES DE LA REACTION CATALYTIQUE. LES SOLUTIONS SOLIDES CEO#2-ZRO#2 ONT DONC A PRIORI LES PROPRIETES REQUISES POUR REMPLACER CEO#2 ; IL RESTE CEPENDANT A DETERMINER SI LE SITE CONTENANT LE RHODIUM OXYDE EST PLUS ACTIF, OU MOINS ACTIF EN REACTION CO-NO-O#2 QU'UN SITE RH(O)

In recent years the need for sustainable process design and alternative reaction routes to reduce industry?s impact on the environment has gained vital importance. The book begins with a general overview of new trends in designing industrial chemical processes which are environmentally friendly and economically feasible. Specific examples written by experts from industry cover the possibilities of running industrial chemical processes in a sustainable manner and provide an up-to-date insight into the main concerns, e.g., the use of renewable raw materials, the use of alternative energy sources in chemical processes, the design of intrinsically safe processes, microreactor and integrated reaction/ separation technologies, process intensification, waste reduction, new catalytic routes and/or solvent and process optimization.
