The reduction behavior and metallization degree of magnetite concentrate with agave bagasse were investigated in an inert atmosphere. The effects of temperature, biomass content, and residence time on reduction experiments and metallization degree were investigated by X-ray diffraction and scanning electron microscopy. Compared with other types of biomass, agave bagasse had lower contents of nitrogen, sulfur, and ash. X-ray diffraction analysis showed that the metallization degree improved with increasing temperature and biomass content. Complete metallization was achieved at 1100°C for 30 min with 65:35 and 50:50 ratios of the magnetite concentrate to the agave bagasse. These results demonstrate that agave bagasse promotes the efficient metallization of magnetite concentrate without the external addition of a reducing agent. Therefore, this biomass is a technical suitable alternative to replace fossil fuels in steelmaking.

研究了在惰性气氛下用龙舌兰蔗渣对磁铁矿精矿的还原行为和金属化程度。通过X射线衍射和扫描电子显微镜研究了温度，生物量和停留时间对还原实验和金属化程度的影响。与其他类型的生物质相比，龙舌兰蔗渣的氮，硫和灰分含量较低。X射线衍射分析表明，金属化程度随温度和生物量的增加而提高。在磁铁矿精矿与龙舌兰蔗渣的比例为65:35和50:50的情况下，在1100°C下完成30分钟的完全金属化。这些结果表明，在没有外部添加还原剂的情况下，龙舌兰蔗渣促进了磁铁矿精矿的有效金属化。所以，
