Abstract

LA INVENCION SE REFIERE A UN PROCESO Y UN DISPOSITIVO PARA LA DEGRADACION DE OXIDOS DE NITROGENO EN LOS GASES DE ESCAPE (A) DE UN MOTOR DE COMBUSTION (2), SEGUN EL CUAL LOS GASES DE ESCAPE (A) Y UN REACTIVO (R) DISPERSO EN ELLOS MEDIANTE AIRE COMPRIMIDO (B) SE CONDUCEN A UN CATALIZADOR (21). A TAL EFECTO, EL MOTOR DE COMBUSTION (2) VA EQUIPADO CON UN COMPRESOR (8) PARA LA INYECCION DE AIRE COMPRIMIDO (1 ), Y SE HA PREVISTO EL DESVIO DE UNA PARTE (D) DEL AIRE COMPRIMIDO (1 ) PARA UTILIZARLO COMO AIRE COMPRIMIDO PARA ATOMIZAR EL REACTIVO (R). EL REACTIVO (R) PULVERIZADO SE CONDUCE JUNTO CON LOS GASES DE ESCAPE (A) A PURIFICAR A UN CATALIZADOR (21), EL CUAL DEGRADA LOS OXIDOS DE NITROGENO, ESPECIALMENTE SEGUN EL PROCESO DE REACCION CATALITICA SELECTIVA.
