Abstract

Se describen compuestos de catalizador de oxidación para el tratamiento de emisiones de gas de escape, tal como la reducción de hidrocarburos sin quemar (HC), y monóxido de carbono (CO) y la oxidación de NO a NO2. Los compuestos de catalizador comprenden dos capas de recubrimiento sellador que contienen dos composiciones diferentes de metales del grupo del platino para optimizar el NO2 que sale del compuesto de catalizador. La clave para la mejorar de la oxidación de NO es tener una capa de catalizador que contenga Pt y que a su vez carece sustancialmente de Pd. También se describen los métodos y sistemas que utilizan compuestos de catalizador.
