The simultaneous removal of sulfur compounds such as H_2S and COS were studied using carbonaceous materials at 400℃. A char obtained as a byproduct in woody biomass gasification, a commercial activated carbon and Fe-supported activated carbon were employed as an adsorbent. The both breakthrough times in the char were approximately 100 times longer compared to that in activated carbon, and approximately 6 times longer compared to that in Fe-supported activated carbon. The physical characterization indicated that the char had a broader pore distribution compared to those of other carbonaceous materials.
