Abstract
Procedimiento de fabricación de un catalizador para el tratamiento de los gases de combustión, caracterizado porque sobre un soporte de material inerte se deposita una capa de óxido de lantano; porque a continuación se deposita rutenio sobre el soporte ya revestido, impregnando a este último con una solución acuosa que contiene una sal soluble de rutenio y reduciendo a continuación durante algunas horas la citada sal impregnada, la cual reducción se lleva a cabo con un gas reducto, a una temperatura del orden de 400 a 700ºC.
