Abstract
A filter is disclosed for treating a gaseous stream to remove therefrom undesirable components, especially from exhaust gases of engines, and particularly from internal combustion engines, such as, for example, Diesel engines and the like. The filter includes a filter body or element having a plurality of inlet and outlet channels, with the inlet channels being separated from the outlet channels by walls or partitions to provide reaction chambers. The filter body is made a high-temperature-resistant, sintering material, and can be made of metal wire or metal chips which are compacted and subsequently sintered.
