Abstract

La presente invención se refiere a un catalizador para la reducción catalítica, selectiva de NOx en un gas residual que contiene metales alcalinos utilizando amoníaco como el agente reductor, el catalizador comprende una superficie con sitios catalíticamente activos, en donde la superficie está revestida por lo menos parcialmente con un recubrimiento que comprende por lo menos un óxido metal. En otro aspecto, la presente invención se refiere al uso del catalizador y a un método para producir el catalizador. Además, la presente invención se refiere a un método para tratar un catalizador para conferir en el mismo una resistencia mejorada al envenenamiento por álcalis. La figura más representativa de la invención es la número 1A.
