Abstract

LA DISMINUCION REDUCTORA DEL CONTENIDO DE OXIDO DE NITROGENO DE GASES DE ESCAPE DE COMBUSTION SE EFECTUA HACIENDO REACCIONAR ESTOS GASES CON UN AGENTE REDUCTOR GASEOSO, PREFERIBLEMENTE AMONIACO, EN PRESENCIA DE UN CATALIZADOR QUE CONTIENE, COMO COMPONENTE ACTIVO, UN SILICATO DE ESTRUCTURA ESTRATIFICADA ACTIVADO CON ACIDO, ESPECIALMENTE DEL TIPO DE ESMECTITA, EFECTUANDOSE LA REACCION A UNA TEMPERATURA DE 250 A 600JC, A UNA VELOCIDAD ESPACIAL DE 500 A 20.000 LITROS DE GAS POR HORA Y LITRO DE CATALIZADOR Y CON UNA RELACION MOLAR DE AGENTE REDUCTOR GASEOSO A OXIDO DE NITROGENO DE APROXIMADAMENTE 0,3 A 3. EL INVENTO ES APLICABLE A GASES DE ESCAPE DE LA COMBUSTION DE MATERIALES FOSILES, TALES COMO CARBON, PETROLEO O GAS NATURAL, Y TAMBIEN A LOS GASES DE ESCAPE DE LOS MOTORES DE COMBUSTION INTERNA.
