    Abstract: Un compuesto catalizador de oxidación para disminuir las emisiones de gases de escape de un motor de combustión pobre que comprende: un sustrato portador que tiene una longitud, un extremo de entrada y un extremo de salida, un material catalítico catalizador de oxidación en el portador, el material catalítico catalizador de oxidación incluye una capa de impregnación inferior y una capa de impregnación superior; la capa de impregnación inferior que comprende un soporte de óxido metálico refractario, un componente de platino (Pt) y un componente de paladio (Pd) en una relación de peso Pt/Pd en el rango de 4:1 a 1:4; y la capa de impregnación superior comprende una zeolita, Pt y un soporte de óxido metálico refractario, la capa de impregnación superior tiene una cantidad de paladio inferior al 10 % en peso del metal del grupo del platino en la capa de impregnación superior, el compuesto catalizador de oxidación es efectivo para disminuir los hidrocarburos y el monóxido de carbono, y oxidar el NO a NO2 en el escape del motor de combustión pobre, y en donde la capa de impregnación superior contiene una mayor carga de metales del grupo del platino que la capa de impregnación inferior para maximizar la oxidación de NO.

    Abstract: Emissions treatment systems of combustion engines are provided, which comprise a platinum-containing catalyst that is degreened during production, which is before exposure to operating conditions of a vehicle having a diesel engine. The platinum-containing catalyst, in the form of a platinum component on a high surface area refractory metal oxide support, exhibits a vibration frequency of about 2085 to about 2105 cm−1 as measured by CO-DRIFTS. Such catalytic material is essentially-free of platinum oxide species found at greater than about 2110 cm−1 as measured by CO-DRIFTS. Such catalysts can provide excellent and consistent conversion of nitrogen oxide (NO) to nitrogen dioxide (NO2).

    Abstract: Provided herein are zoned catalysts that utilize components efficiently in that relatively short zones are provided to achieve specific functionalities to convert and/or trap one or more components in the exhaust stream. Highly controlled zoned are formed from one end of a monolithic carrier. The zones have a flat profile such that the zoned catalytic material within each passage of the substrate is at a substantially uniform distance from one end of the carrier. Methods of making and using the same are also provided.
