To prevent performance degradation of biogas-fueled SOFC caused by H2S poisoning, this study aimed to develop a nitrogen (N)-doped carbon derived from biomass feedstock, which acted as an adsorbent of H2S. Biochar (BC) derived from rice husk (RH) treated with 25 vol% NH3gas at 900°C for 120 min, exhibited the largest H2S breakthrough capacity (ACPH2S(0)) of 8.02 mg H2S g- BC-1 and a total H2S adsorption capacity (ACPH2S) of 9.58 mg H2S g-BC-1. The largest ACPH2S, 23.0 mg H2S g-BC-1, was obtained for the RH-BC treated with NH3evaporated from a 10 wt% NH3solution (simulating a concentrated digested liquid) at 850°C for 270 min. For a mildly N-doped BC, the interaction of the surface with H2S was moderately weakened, preventing the blockage of micropore openings by the accumulation of sulfate.
