No.22 Desulfurization-Methane Reforming in the Presence of H_2O and at High Temperature for Biomass Gasification and BTL Synthesis

Abstract

Process simulation indicated that successive biomass-gasification and methane-reforming improved efficiency and cost of gasification-catalytic fuel synthesis, such as bio-FT-oil and bio-LPG. Laboratory-designed Rh-Ni/Sr/ZrO_2 catalyst effectively reformed methane in both test-gas and bio-syngas, however it was deactivated within several hours when applied to the bio-syngas because of being toxificated by sulfur compounds in it, such as H_2S. Pretreated ALC was found to desulfurize hot gas with high steam content, although no other desulfurizing agents were operable in such severe conditions. Experimental results of the catalytic methane-reforming and the ALC desulfurizing were discussed in this manuscript. Their combined process is now planned.
