Abstract
La presente invención se refiere a un catalizador monolítico o respectivamente en forma de panal de abeja, especialmente para purificar los gases de escape de máquina de combustión, consistente de un soporte inerte, cerámico o metálico, atravesado por canales conductores paralelos, una capa dispuesta sobre el mismo, de óxido metálico promovedor de la catálisis y un componente catalíticamente activo sostenido por el óxido metálico, caracterizado porque, la concentración del óxido metálico promotor de la catálisis aumenta desde la periferia al eje medio del soporte.
