Abstract

EN EL PROCESO DE FABRICACION DEL CATALIZADOR QUE PURIFICA EL GAS DE ESCAPE (3), SE PORTA RODIO MEDIANTE EL MATERIAL BASE UTILIZANDO LA SOLUCION DE GRUPOS CARBONILO DE RODIO EN LA QUE SE DISUELVE UN GRUPO CARBONILO DE RODIO EN METANOL, EN LA ETAPA DE FORMACION DE LA CAPA SUPERIOR CATALITICA (6), QUE INCLUYE RODIO Y PLATINO COMO METALES CATALITICOS. MEDIANTE ESTO, SE ELEVA ALTAMENTE LA DISPERSIBILIDAD DEL RODIO EN EL MATERIAL BASE, Y SE INHIBE EFICAZMENTE RODIO ADICIONAL DE SER OXIDADO DURANTE EL PROCESO DE FABRICACION DEL CATALIZADOR (3). ASI, DE ACUERDO CON EL CATALIZADOR QUE PURIFICA EL GAS DE ESCAPE (3), ESPECIALMENTE, SE MEJORA ALTAMENTE EL RENDIMIENTO PURIFICANTE DEL NOX, TANTO A LA TEMPERATURA INFERIOR DEL GAS DE ESCAPE, COMO A LA TEMPERATURA SUPERIOR DEL GAS DE ESCAPE.
