Abstract

Se describen sistemas de catalizadores para reducción catalítica selectiva (RCS) que comprenden una primera composición de catalizador para RCS y una segunda composición de catalizador para RCS colocadas en el sistema, en los que la primera composición de catalizador para RCS promueve una mayor formación de N2 y una menor formación de N2O que la segunda composición de catalizador para RCS, y la segunda composición de catalizador para RCS tiene una composición diferente a la primera composición de catalizador para RCS, donde la segunda composición de catalizador para RCS promueve una menor formación de N2 y una mayor formación de N2O que la primera composición de catalizador para RCS. Los sistemas de catalizadores de RCS son útiles en los métodos y sistemas para catalizar la reducción de óxidos de nitrógeno en presencia de un reductor.
