Abstract

UN CATALIZADOR PARA LIMPIAR LOS GASES DE ESCAPE DE MOTORES DE COMBUSTION INTERNA, ESPECIALMENTE MOTORES DIESEL, COMPRENDE UN CUERPO MONOLITICO QUE TIENE ABERTURAS , QUE SE EXTIENDEN LONGITUDINALMENTE, A TRAVES DE CANALES CUBIERTOS CON UNA CAPA DE REVESTIMIENTO DELGADO QUE ENSANCHA LA SUPERFICIE LA CUAL CONTIENE UNO O MAS METALES PRECIOSOS ACTIVOS CATALITICAMENTE. PARA REDUCIR LA TENDENCIA DEL CATALIZADOR A OXIDARSE Y ABSORBER (SER ENRIQUECIDO CON) EL DIOXIDO DE AZUFRE, LA CAPA DE REVESTIMIENTO DEL CATALIZADOR ESTA BASADA EN CARBURO DE SILICIO Y ES SUSTANCIALMENTE LIBRE DE OXIDO DE ALUMINIO. SON TAMBIEN DESCUBIERTOS UN METODO PARA PREPARAR EL CATALIZADOR, EL USO DEL CATALIZADOR, COMO TAMBIEN UN SISTEMA DE LIMPIEZA DE GASES DE ESCAPE Y UN VEHICULO A MOTOR EQUIPADO CON EL CATALIZADOR.
