Abstract

Se describe una trampa de NOx pobre para el tratamiento de emisiones de gas de escape, tal como la oxidación de hidrocarburos sin quemar (HC) y monóxido de carbono (CO), y el entrampado y la reducción de óxidos de nitrógeno (NOx). Los catalizadores de almacenamiento de óxido de nitrógeno pueden comprender una capa sobre un sustrato que incluye partículas de óxido de cerio-alúmina con una fase de óxido de cerio presente en un porcentaje en peso de la mixtura en el intervalo de alrededor de 20 % a alrededor de 80 % con base en óxido, un componente de metal alcalinotérreo con soporte en las partículas de óxido de cerio-alúmina, donde el CeO2 se encuentra presente en forma de cristalitas que son estables desde un punto de vista hidrotérmico y tienen un tamaño de cristalita promedio menor que 130 Å luego del envejecimiento a 950 °C durante 5 horas en O2 al 2 % y vapor al 10 % en N2.
