Iron-based oxygen carriers (OCs) have received much attention due to their low costs, high mechanical strengths and high-temperature stabilities in the chemical looping gasification (CLG) of biomass, but reactivity is very ordinary. Converter steel slags (CSSs) are steelmaking wastes rich Fe2O3, CaO MgO, which good oxidative ability stability as well catalytic effects on biomass gasification. Therefore, composite OCs prepared by mechanically mixing CSSs with iron-based expected be used increase hydrogen production CLG biomass. In this study, performance CSS/Fe2O3 brewers’ spent grains (BSGs) were investigated a tubular furnace experimental apparatus. The results showed that when weight ratio was 0.5, relative volume fraction reached maximum value 49.1%, product gas yield 0.85 Nm3/kg efficiency 64.05%. It could found X-ray diffraction patterns scanning electron microscope characterizations addition helped form MgFe2O4, efficient catalysts for H2 production. Owing large widely distributed surface pores CSSs, them beneficial steam reforming produce hydrogen.
