Abstract This study is devoted to the reduction of Fe2O3 supported on silica gel in H2 in the temperature range of 290–600 °C. A continuous magnetization measurement method was used to obtain the temperature programmed reduction (TPR) profile. The influence of the external magnetic field on the dynamics of the process is investigated. It was shown that the TPR profile depends both on the magnitude of the applied field and on the particle size of hematite.

磁法研究赤铁矿还原动力学

摘要 本研究致力于在 290–600 °C 的温度范围内在 H2 中还原硅胶上负载的 Fe2O3。使用连续磁化测量方法获得程序升温还原 (TPR) 曲线。研究了外部磁场对过程动力学的影响。结果表明，TPR 分布取决于施加场的大小和赤铁矿的粒度。
