Abstract

Abstract: Conventional steam reforming for hydrogen production is limited by the thermodynamic equilibrium. To address this limitation, in this study, a cost-effective catalyst-sorbent hybrid material was synthesized from waste steel slag and limestone. A 30-cycle CO₂ sorption experiment and a sorption-enhanced biomass reforming for hydrogen production experiment were conducted. The results indicate that for the A₄L₃S₂ (4 mol·L^-1 acid, limestone: slag = 3:2) composite, it attains a total CO₂ sorption capacity of 4.14 g·g^-1 under mild conditions, with only a 23.5% reduction after 30 cycles. Moreover, under severe conditions, it manages to retain 3.81 g·g^-1 in total 30 cycle. When applied to sorption-enhanced biomass gasification using pine wood shavings, the material significantly boosts hydrogen production, achieving a hydrogen purity of 74.57% and a yield of 0.818 mmol·g·g^-1·min^-1, while reducing the CO₂ concentration in the syngas to 10.89%. These findings highlight the dual functionality and robustness of the steel slag-derived material, offering a cost-efficient and environmentally sustainable pathway for industrial hydrogen production and valorization of solid waste resources.
