Abstract: The pilot scale experimental installation for SO2 removal by activated carbons has been built. The effect of molar heat on SO2 removal at high concentrations has been investigated. The results showed that the adsorption of SO2 was the main reason of the temperature rise in the carbon bed. Meanwhile the temperature rise of the hot spot was due to the oxidation of carbon. Thanks to the adoption of the moving bed, the circulation of activated carbon was an effective way to lower temperatures as well as temperature deviations. In more detail, this method had insignificant effects on the adsorption of SO2 and the pressure drop of the bed. The heat transfer of the hot spot was effectively controlled by the cooling system. However, the ventilation would make situation worse.
