Abstract
Se describen sistemas de tratamiento de gases de escape para tratar un flujo de gases de escape de motor de gasolina que contiene NOx, materia particulada y azufre. El sistema de tratamiento de gases de escape comprende: uno o más artículos catalíticos seleccionados de un catalizador de conversión de tres vías (TWC), una trampa de NOx pobre (LNT) y LNT-TWC integrados; un artículo catalítico que contiene platino corriente abajo del uno o más artículos catalíticos; y uno o más artículos catalíticos de reducción catalítica selectiva (SCR) inmediatamente corriente abajo del artículo catalítico que contiene platino, en donde el uno o más artículos catalíticos de SCR incluyen un tamiz molecular. El sistema estabiliza el artículo catalítico de SCR del envenenamiento con azufre.
