Abstract

UNA COMPOSICION CATALITICA DE CONVERSION DE TRES PASOS DE UN METAL DEL GRUPO DEL PLATINO QUE CONTIENE UN COMPONENTE CATALITICO DE ALTA TEMPERATURA Y UN COMPONENTE CATALITICO DE BAJA TEMPERATURA ESTANDO CADA COMPONENTE CATALITICO PRESENTE A MODO DE PARTICULAS DISTINTAS INDEPENDIENTES EN LA MISMA CAPA DE REVESTIMIENTO DELGADO. LA COMPOSICION CATALITICA SE PREPARA A PARTIR DE UNA LECHADA DE REVESTIMIENTO DELGADO QUE CONTIENE UN MATERIAL DE SOPORTE CATALITICO DE ALTA TEMPERATURA Y UN MATERIAL DE SOPORTE CATALITICO DE BAJA TEMPERATURA TENIENDO CADA MATERIAL DE SOPORTE UN TAMAÑO DE LAS PARTICULAS LO SUFICIENTEMENTE GRANDE COMO PARA IMPEDIR QUE CADA MATERIAL DE SOPORTE FORME UNA SOLUCION O UN SOL CON EL ELEMENTO LIQUIDO DE LA LECHADA. EL METAL O METALES DEL GRUPO DEL PLATINO SE PUEDEN IMPREGNAR EN CADA MATERIAL DE SOPORTE BIEN TRAS LA FORMACION DEL REVESTIMIENTO DELGADO SOBRE UN SUBSTRATO REFRACTARIO NO POROSO, METALICO O EN GRANULOS O BIEN ANTES DE FORMAR LA LECHADA DE REVESTIMIENTO DELGADO.
