Abstract
Se describen sistemas y métodos de catalizadores de RCS que comprende una primera composición de catalizador para RCS y una segunda composición de catalizador para RCS colocadas en el sistema, donde la primera composición de catalizador para RCS tiene un tiempo de respuesta de DeNOx más rápido cuando se expone a amoníaco que la segunda composición de catalizador y la segunda composición de catalizador para RCS tiene un rendimiento de DeNOx en estado estacionario superior a la primera composición de catalizador. 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.
