Abstract

Nuevo catalizador para la reducción de NO a N_{2} con hidrógeno en condiciones de NO_{x} oxidantes.
Nuevo catalizador que presenta actividad, selectividad y estabilidad excelentes para la reducción de óxido nítrico a nitrógeno gas con hidrógeno como agente reductor en el rango de temperaturas bajas de 100-200°C y en presencia de exceso de oxígeno (p.ej. 5% vol), H_{2}O (5% vol) y/o SO_{2} (20 ppm), en la alimentación.
El catalizador consiste en cristales de platino en contacto con las fases de un soporte mixto de MgO y CeO_{2} o en forma de platino soportado sobre el soporte mixto MgO-CeO_{2} previamente sulfatado de forma selectiva.
Con el catalizador Pt/MgO-CeO_{2} se obtienen niveles de conversión de NO superiores a 40% y valores de selectividad de nitrógeno por encima del 80% en condiciones de NO_{x} oxidantes en el rango de temperatura 100-400°C y con un tiempo de contacto superficial de 0.045 s. En particular, se obtiene conversión completa de NO y niveles de selectividad a N_{2} de 83% a 150°C con una mezcla de reacción de 0.25% NO/1%H_{2}/5%O_{2}/5%H_{2}O/He.
