The SO2 sorption properties of dry potassium-based sorbents, prepared by impregnation of various supports with potassium carbonate, were investigated at the various water vapor concentrations at a level of 5000ppm of SO2. It was found that alkali metal-based sorbents promoted with potassium carbonate could be used as a sorbent for SO2 sorption at low temperatures (between 30°C and 60°C). In particular,...
