The simulation work is dedicated to the multidispersed adsorption-catalytic packing, consisting of comparatively large pellets (say, 5-10 mm) of the catalyst-adsorbent and of catalytically active micro-fibers with typical thickness of ~10 microns. During the heating at the regeneration stage the micro-fiber catalyst must be heated much more rapidly than adsorbent-catalyst, due to the much higher unit outer surface area improving the heat exchange. When the adsorbent-catalyst temperature is becoming high enough for partial desorption of chemisorbed VOC, the temperature of the micro-fibrous catalyst will be already as high as necessary one for complete oxidation of desorbed VOCs. This theoretical concept …

The work is dedicated to the development of the efficient catalyst for the oxidation of CO in presence of significant amounts of SO2. It was experimentally shown that the Pt/Zr-Si glas-fiber-based catalyst is capable to provide complete CO conversion in SO2 presence at temperatures less 300 С, at the same time showing high resistance to deactivation. Application of such catalyst in the reverse-process will allow to raise essentially efficiency of purification of waste metallurgical gases from SO2 under presence of significant amounts (up to 1-2% vol.) of CO.
