| Abstract Scope |
Traditional ironmaking relies on fossil reductants, incurring high energy consumption and carbon emissions. To achieve China's ‘peak carbon’ and ‘carbon neutral’ targets, biomass offers a promising renewable alternative to the reductant required for the preparation of direct reduced iron (DRI). This study investigates biomass-based DRI production, systematically evaluating the reduction of magnetite ore using four biomass types (walnut shell, coconut shell, northeast pine wood, and corn straw) under varied conditions. Key metrics were metallization rate and microstructural evolution. Results reveal significant differences in reduction capability among the biomass types. Increasing the biomass-to-magnetite ore mass ratio generally enhanced metallization, with walnut shell exhibiting optimal performance. Under optimized conditions (C/Fe mass ratio of 0.8, 1100°C, 60 min in N₂), an iron grade of 91.77% and a high metallization rate of 93.42% were achieved for DRI, demonstrating the viability of biomass for low-carbon ironmaking. |
