Abstract
The reduction of nitrogen oxides in gas is carried out, by means of selective reaction of the nitrogen oxide with the reducing agent in the in the solid catalyst. In order to achieve high catalytic activity, the above is carried out at high gas temperatures. As a rule, ceramic filter elements, coated with catalytic material are used. This does, however, give rise to the risk the catalytically active components are stripped from the filter during the hot gas filtration. A ceramic filter element with support material in the form of particles, with binder material and catalytic material is thus disclosed, whereby the binder material comprises catalytic material, or the binder material is partly replaced by the catalyst material and the support material particles () are connected to each other by means of the catalyst and/or binder material.
