Abstract

PROCEDIMIENTO PARA LA ELIMINACION SELECTIVA DE OXIDOS DE NITROGENO A PARTIR DE GASES DE ESCAPE. CONSISTE EN LA UTILIZACION DE UN AGENTE REDUCTOR Y DE CUERPOS SOLIDOS QUE ACTUAN CATALITICAMENTE, LOS CUALES EN VIRTUD DE SU CONSTITUCION ESTRUCTURAL Y POR ESTRUCTURACION COMO LECHO AMONTONADO A GRAN EL PUEDEN SER ATRAVESADOS POR LAS CORRIENTES DE LOS GASES DE ESCAPE. EL AGENTE REDUCTOR, EVENTUALMENTE UNA MEZCLA CON UN GAS PORTADOR, Y LOS GASES DE ESCAPE, QUE CONTIENEN LOS OXIDOS DE NITROGENO QUE SE HAN DE REDUCIR, SE PONEN EN CONTACTO PERIODICAMENTE DE MODO ALTERNADO CON EL CUERPO SOLIDO QUE ACTUA CATALITICAMENTE O CON TRAMOS DEL MISMO. DE APLICACION EN LA ELIMINACION SELECTIVA DE OXIDOS DE NITROGENO EN LOS GASES DE ESCAPE DE INSTALACIONES DE CALDEO Y COMBUSTION.
