Abstract
Solid oxide fuel cells (SOFCs) running on biogas can undergo performance degradation if a trace H2S is present in the fuel. Here, nitrogen-doped rice husk biochar was employed as a sustainable material for desulfurization of biogas via adsorption. The biochar was doped with nitrogen using NH3 evaporated from ammonia solution, as a simulated digestate liquid, and this was found to significantly improve H2S adsorption. Furthermore, the total H2S adsorption capacity was 2.3 times higher compared to biochar treated with a pure NH3 gas source. This improvement was attributed to lower pyridinic-N content, leading to a lower degree of O* radical formation, and ultimately, better micropore utilization.
