ABSTRACT:
Process for adsorbing undesirable constituents from a waste gas by feeding the waste gas through at least one reaction chamber filled with lumpy or granular adsorbent, and through at least one adsorption layer. The adsorbent is introduced into the reaction chamber and discharged therefrom through several separate feed and discharge hoppers in a grid-like distribution. The waste gas is guided in part from the side transversely to the adsorption layer and in part vertically through the reaction chamber by introducing the waste gas between the separate feed hoppers from above to flow downward through an exposed upper surface of the adsorbent in such a manner that the adsorbent in all zones of the reaction chamber participates practically uniformly in the adsorption.
