(1)在本实验条件下，反应温度和碳铵用量对浸出过程都有一定的影响。在忽略液相传质影响的情况下，反应温度和碳铵用量越高，浸出效果越好； (2)在本研究范围之内，RE2(CO3)3的浸出过程是受固膜内扩散过程控制的，其反应级数为0.0998，反应的表观活化能为8.5166kJ/mol，其宏观动力学方程可以描述为 |

(1) In this experimental condition,reaction temperature and the amount of ammomium carbonate both have certain effects to the leaching process. If we disregard the influence of the liquid phase mass transfer, the higher the reaction temperature and the amount of ammomium carbonate are, the better the leaching process would be. (2)In this study area, the leaching process of RE2(CO3)3 is controlled by the solid-membrane diffusion process. Its reaction order is 0.0998. The apparent activity energy of the reaction is 8.5166kJ/mol, and its macroscopic dynamic equation can be described as......  [ Last edited by ymljl on 2010-1-22 at 15:02 ] |
