Abstract
Method and means for modifying gases or fumes fed through a filter (), from its inlet side to its outlet side, submitted to an electric plasma having its maximum plasma density (d) at the filter's inlet side. The gases or fumes may comprise NO, the filter being constituted by a catalytic material fit for modifying NO. The filter also may be polluted with e.g. a soot deposit, precipitated on the filter's surface and/or within the filter's interior. The means may comprise a first electrode system () at the filter's inlet side and a second electrode system () at the filter's outlet side, connected to a high voltage (V). Preferably the first electrode system comprises two or more groups of interlacing electrodes, each connected to a high voltage source (V, V, V).
