搜集并评估了氢气还原铁氧化物反应的表观活化能。分析了反应动力学条件与反应机理和表观活化能的关系。得出：气体内扩散控速和铁离子固态扩散控速时，还原过程的表观活化能分别为８．０～２８．０ ｋＪ／ｍ ｏｌ和＞ ９０ ｋＪ／ｍ ｏｌ；界面化学反应控速时，将Ｆｅ２Ｏ３，Ｆｅ３Ｏ４ 和‘ＦｅＯ’还原为Ｆｅ的表观活化能分别为４０．０～７０．０ ｋＪ／ｍ ｏｌ，５５．０～６５．０ ｋＪ／ｍ ｏｌ和４２．０～５２．０ ｋＪ／ｍ ｏｌ；两个环节混合控速时，表观活化能介于每个环节单独控速的表观活化能范围之间。
The apparent activation energy of the hydrogen-reduced iron oxide reaction was collected and evaluated. The relationship between reaction kinetics and reaction mechanism and apparent activation energy was analyzed. The results show that the apparent activation energies of the reduction process are 8.0 ~ 28.0 kJ / mol and> 90 kJ / mol for gas diffusion control and solid state diffusion control of iron ions respectively. The velocity of interface chemical reaction , The apparent activation energies for the reduction of Fe2O3, Fe3O4 and FeO to Fe are 40.0-70.0 kJ / mol, 55.0-65.0 kJ / mol and 42.0-52, respectively. 0 kJ / mol; the apparent activation energy in the mixed control of two stages is between the range of apparent activation energy of the individual controlled speed in each stage.
