铬铁矿熔盐液相氧化新反应系统的热力学分析

Thermodynamic analysis on new reaction system of liquid phase oxidation of chromite in molten salt

利用自编的热力学计算软件对铬铁矿熔盐液相氧化过程进行了热力学计算与分析， 通过与传统铬盐生产方法中的碳酸钠高温氧化焙烧过程的比较表明， 在较低温度下， 液相氧化新过程具有很强的反应趋势、大的放热量及极宽的反应条件， 大大优于现行铬盐生产的传统焙烧过程。

Using the thermodynamic calculation software designed by the author, the thermodynamic calculation and analysis of the new process of liquid phase oxidation of chromite show that the new process holds strong reacting tendency, high exothermic quantity and wide reaction conditions at low temperature. In comparison with the conventional high temperature roasting process for present chromate production using sodium carbonate as reaction media, the process of liquid phase oxidation of chromite in the molten salt of sodium hydroxide is much more advantageous.
