Abstract

Se proporciona un artículo de catalizador de oxidación diésel, que incluye un portador de sustrato que tiene una pluralidad de canales adaptados para el flujo de gas y una composición de catalizador posicionada para contactar un gas de escape que pasa a través de cada canal. La composición de catalizador incluye un componente de platino (Pt) y un componente que contiene azufre (S) impregnado sobre un soporte de óxido de metal refractario y es eficaz para reducir el hidrocarburo y el monóxido de carbono, así como para oxidar NO a NO2 en el gas de escape. También se proporcionan métodos para fabricar y utilizar el artículo de catalizador, así como sistemas de tratamiento de emisión que comprenden el artículo de catalizador.
