Abstract
Se describen filtros de partículas revestidos y métodos para su fabricación; los filtros de partículas comprenden un cuerpo de panal que tiene una pluralidad de paredes porosas de canal que definen canales que se extienden desde un extremo de entrada a un extremo de salida; el cuerpo de panal tiene una zona corriente arriba que tiene una permeabilidad a los gases de zona corriente arriba y una zona corriente abajo dispuesta más cerca del extremo de salida que la zona corriente arriba y que tiene una permeabilidad a los gases de zona corriente abajo; el catalizador SCR está presente en una carga en la zona corriente abajo a una carga localizada en una escala de aproximadamente 50 g/L a aproximadamente 200 g/L de manera que la permeabilidad a los gases de la zona corriente arriba está en una escala de aproximadamente 5 a aproximadamente 90 veces la permeabilidad a los gases de la zona corriente abajo.
