Abstract (en)
[origin: DE4410142A1] A filtering material, in particular for polar and homopolar gasses, such as hydrocarbon compounds, sulphur dioxide and/or nitrous gasses, consists of a granulate that at least partially contains active coal. In order to achieve a high degree of adsorption, the filtering material contains a heterogeneous mixture of active coal granulate and at least one metal oxide granulate or a granulate made of active coal with at least one metal oxide.
