Preparation and Characterization of Reactive Adsorbents -Analysis of the Reaction ProcessThe removal of undesired gases can be realized by a dry separation through a packed bed of particulate adsorbents. Shaped solids containing potassium permanganate as active component were prepared by extrusion and used for the deposition of the model pollutant H 2 S. The extrudates were characterized with respect to the mechanical stability and the separation efficiency by breakthrough curves. These experiments show a breakthrough of the extrudate bed before the adsorbents have reacted completely. Apparently, the gas only slowly intrudes into the extrudate, so the reaction takes place mainly near the outer surface.
