Abstract
PROCEDIMIENTO PARA REDUCIR EL CONTENIDO DE OXIDOS DE NITROGENO EN GASES RESIDUALES DE INSTALACIONES DE COMBUSTION. CONSISTE EN CONDUCIR LOS GASES RESIDUALES QUE CONTIENEN OXIDO DE NITROGENO A LO LARGO DE ESTRUCTURAS LAMINARES ESTABLES A LA TEMPERATURA QUE HAN SIDO REVESTIDAS CON UNA MEZCLA DE UNO O VARIOS ALUMINOSILICATOS DEL GRUPO FAUJASITA, SAL DE SILICE Y/O SILICATOS Y DE UN COMPUESTO DE COBRE, CONTENIENDO ADICIONALMENTE FIBRAS DE VIDRIO; EFECTUANDOSE LA REDUCCION CATALITICA SUBSIGUIENTE A UNA TEMPERATURA COMPRENDIDA ENTRE 100 Y 250JC; EMPLEANDO COMO ESTRUCTURAS LAMINARES PLACAS PRENSADAS SILICATOSAS, ESTABLES A LA TEMPERATURA, USUALES EN EL MERCADO, DEL GRUPO DE LOS SILICATOS DE CALCIO, Y DISPUESTAS PARALELAS ENTRE SI A UNA DISTANCIA DE 0,1 HASTA 2 CM. TIENE APLICACION EN INSTALACIONES DE COMBUSTION, TALES COMO CENTRALES TERMICAS CALENTADAS POR GAS NATURAL, ACEITE O CARBON, POR RAZONES DE PROTECCION DEL MEDIO AMBIENTE.
