The invention especially relates to components used as ceramic catalysts in denitration plants. In said plants, the catalysts are impinged upon by low frequency sound. This enables the surfaces of the catalysts to be cleaned and simultaneously enhances their efficacy. If the catalysts cannot be reactivated they are subjected to final intensive cleaning wherein they are exposed once more to low frequency sound. Subsequently the catalysts are crushed and the , ceramic material can be used in all cases where the chemical properties of the material is of no particular significance. The cleaned particles containing pollutants are dumped or disposed of in melting chamber furnaces.
