Abstract
LA INVENCION SE REFIERE A UN METODO PARA EL TRATAMIENTO CATALITICO DE GASES CON ELEVADO CONTENIDO EN OXIGENO QUE REDUCE LAS EMISIONES DE OXIDOS DE NITROGENO Y QUE SE CARACTERIZA PORQUE UTILIZA UNA COMPOSICION CATALITICA QUE COMPRENDE OXIDO DE MANGANESO Y AL MENOS UN OXIDO ELEGIDO ENTRE EL OXIDO DE CERIO Y EL OXIDO DE CIRCONIO. ESTA COMPOSICION PUEDE INCLUIR, ADEMAS, AL MENOS OTRO ELEMENTO ELEGIDO ENTRE LOS GRUPOS VIII, IB, IVB Y VB. EL METODO DE LA INVENCION SE APLICA ESPECIALMENTE AL TRATAMIENTO DE GASES DE ESCAPE DE MOTORES DE COMBUSTION INTERNA, ESPECIALMENTE DE MOTORES DIESEL O DE MOTORES QUE FUNCIONAN CON MEZCLAS POBRES.
