Abstract
Sulfidation and sulfation reactions of Daesung limestone, which is a calcium-based sorbent chosen out of domestic limestone for the removal of H2S and SO2, were investigated by using TGA (thermal gravimetric analyzer). Effects of H-2 and H2S on the sulfidation were also investigated. The conversion rate of CaS to CaSO4 in oxidation was low since the concentration of SO2 used fur this study was low and CaO was not completely converted into CaS. It was observed that the effects of H-2 concentration on the sulfidation were relatively small and the maximum conversion rate and reaction rate increased with increase of H2S concentration. In the sulfation reaction, conversion rate could be raised with the injection of air at a sulfation reaction temperature above 800 degrees C. However. the conversion rate decreased without the injection of air due to the blockage of sorbent pores.
