Abstract

Se describen sistemas de catalizadores para RCS que comprenden una primera composición catalizadora para RCS y una segunda composición catalizadora para RCS dispuestas en el sistema, la primera composición catalizadora para RCS promueve una formación más alta de N2 y una formación más baja de N2O que la segunda composición catalizadora para RCS, y la segunda composición catalizadora para RCS tiene una composición diferente que la primera composición catalizadora para RCS, la segunda composición catalizadora para RCS promueve una formación más baja de N2 y una formación más alta de N2O que la primera composición catalizadora para RCS. Los sistemas de catalizadores para RCS son útiles en métodos y sistemas para catalizar la reducción de óxidos de nitrógeno en presencia de un reductor.
