摘要
利用X-ray衍射和失重法研究了CO/CO2混合气体还原氧化铁过程中Fe3C的生成规律,得到3Fe+2CO=Fe3C+CO2的反应标准自由能表达式为:△G°=-151 470+168.78T,绘制了碳化铁生成热力学平衡图,与实验结果基本吻合。
The formation of FeaC during reduction of iron oxide in CO/CO2 mixture gas was investigated by means of X-ray diffiraction tbermogravimetric analysis. Stadard Gibbs Energy of the formation was obtained, which is in accord with the experimental results.
