Abstract
Método para el tratamiento de los gases de escape que contiene óxidos de nitrógeno, oxigeno y hollín, en el que los óxidos de nitrógeno son reducidos selectivamente a nitrógeno, añadiendo amoniaco al gas de escape como agente reductor, en presencia de un catalizador, caracterizado porque el oxido de nitrógeno se separa introduciendo el gas de escape en un reactor de desnitracion que comprende una pluralidad de cuerpos catalizadores planos o cuerpos catalizadores provistos de orificios de paso del gas, seleccionando la velocidad lineal del gas a través del reactor de 4 a 15 m/s.
