Abstract

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 was confirmed by results of the mathematical simulation of combined multi-dispersed system. It was shown, that addition of the microfibrous catalyst leads to significant improvement of the purirfication efficiency of the adsorption-catalytic process.
