氧化物杂质对铁氧化物还原动力学的影响

Influence of Foreign Oxides on Reduction Kinetics of Iron Oxides

系统分析了氧化物杂质对铁氧化物还原动力学的影响及其机理。发现 :各种杂质影响的特点与杂质浓度、存在形态和 /或加入方法 ,样品的初始化学组成和物理性状 ,还原剂的种类、反应温度、还原分数等多种因素有关。

The influences of foreign oxides on reduction kinetics of iron oxides were analysed systematically. It has been noted that the influences relate with many experimental conditions involving the concentrations of foreign oxides, existing states and/or doping methods, the chemical composition and physical properties of the initial specimen, the reducing gas, reaction temperature as well as reaction fraction.
