Abstract

Es wird ein Verfahren zum Entfernen von Rußpartikeln aus einem Abgasstrom von Verbrennungsmotoren in einem Modul (1) durch Oxidation der temporär in einer Katalysatoranlage eingefangenen Rußpartikel mit Stickstoffdioxid (NO2) angegeben, wobei das Stickstoffdioxid durch Oxidation des im Abgas vorhandenen Stickstoffmonoxids (NO) an einem Katalysator (2) in Abhängigkeit von der Strömungsgeschwindigkeit des Abgases bei einer Temperatur oberhalb von ca. 200° C gebildet wird. Dabei wird das Abgas durch zumindest zwei eine Stickstoffdioxid-Konzentration im Abgas erhöhende edelmetallbeschichtete offenporige Metallschäume (2) sowie diesen nachgeschaltete offenporige Metallschäume (3,4) geleitet.
