摘要: The research on biomass reduction of Fe2O3 was carried out by using sawdust as reductant. The direct reducing agents in the biomass magnetization process were determined by comparing various biomass pyrolysis products with the reduction degree (divalent iron content in total iron), reduction temperature range and valence change of Fe2O3 in the reduction process. The microstructure variation of Fe2O3 at different stages was also analyzed by scanning electron microscopy (SEM). Nonisothermal thermogravimetric analysis (TGA) was applied to explore the thermal reduction process. The results show that the direct reducing substances in the biomass reaction with Fe2O3 are H2 and bio-oil, and the reduction process can be divided into two steps: biomass pyrolyzing to release H2 and bio-oil, and reductive volatiles reacting with Fe2O3. The two steps are relatively independent. The kinetic of the reduction reaction follows a first-order reaction kinetic model, with 88.99 kJ/mol activation energy and 9.55 × 108 min ?1 frequency factor.
