| 摘 要： | 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.

| Abstract: | The reduction behavior and metallization degree of magnetite concentrate with agave bagasse were investigated in an inert atmo-sphere. 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℃ 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 re-ducing agent. Therefore, this biomass is a technical suitable alternative to replace fossil fuels in steelmaking. |
