Abstract
(DE)
Verfahren zur Herstellung von Partikelfiltern. Partikelfilter werden gemeinhin zur Filterung von Abgasen aus einem Verbrennungsprozess eingesetzt. Die vorliegende Erfindung ist auf ein Verfahren zur Herstellung eines beschichteten Wandflussfilters, einem nach diesem Verfahren hergestellten Wandflussfilter und die Verwendung des Wandflussfilters in einem Verfahren zur Minderung schädlicher Komponenten in einem Gasstrom gerichtet. Ebenfalls angegeben werden neue Filtersubstrate sowie deren spezifische Verwendung in der Abgasnachbehandlung.
(EN)
The invention relates to a method for producing particle filters. Particle filters are commonly used for filtering exhaust gases from a combustion process. The present invention relates to a device for producing a coated wall flow filter, to a wall flow filter produced according to this method and to the use of the wall flow filter in a method for reducing harmful components in a gas stream. Also disclosed are new filter substrates and their specific use in the exhaust gas aftertreatment.
