Abstract

CATALIZADOR QUE SE UTILIZA PARA PURIFICAR LOS GASES DE ESCAPE DE UN MOTOR DE COMBUSTION INTERNA DE UN AUTOMOVIL O SIMILAR Y QUE PUEDE MOSTRAR UN FUNCIONAMIENTO EXCELENTE EN CUANTO A LA PURIFICACION, INCLUSO DESPUES DE UN SERVICIO PROLONGADO Y A ALTA TEMPERATURA. EL CATALIZADOR SE COMPONE DE UN COMPONENTE CATALITICO QUE COMPRENDE AL MENOS UN ELEMENTO DE GRUPO DE PLATINO, ALUMINA ACTIVADO, OXIDO DE CERIO, UN OXIDO DE ZIRCONIO COPRECIPITADO ESTABILIZADO POR CERIO, Y OPCIONALMENTE, UN COMPUESTO DE ZIRCONIO SOBRE UN APOYO MONOLITICO. ESTE CATALIZADOR SE PRODUCE PREPARANDO ALUMINA ACTIVADA, QUE CONTENGA AL MENOS UN ELEMENTO DE GRUPO DE PLATINO, AÑADIENDO A LA MISMA OXIDO DE CERIO, UN OXIDO COPRECIPITADO DE CIRCONIO ESTABILIZADO POR CERIO, Y OPCIONALMENTE, UN COMPUESTO DE CIRCONIO PARA PREPARAR UNA LECHADA, Y APLICARLA SOBRE UN SOPORTE MONOLITICO, SEGUIDO DE UN ENCENDIDO.
