将氧通过界面反应在两相间的传递过程简化为界面化学反应和扩散传质两个步骤,对此过程的动力学进行了数学解析, 得到了一个新的动力学模型. 同时显示, 反应过程中界面氧浓度随反应过程的进行不断发生变化, 这表明该界面反应是一个非平衡过程. 应用得到的动力学模型对几个体系的动力学实验数据进行了拟合,符合很好, 根据拟合的参数可以很好地解释实验现象. 初步讨论了模型参数的意义和对动力学过程的影响.
Divided into two steps of a chemical reaction and a mass transfer process, the interfacial kinetics of oxygen transfer between two phases has been resolved mathematically, and a kinetic model has also been obtained. It was shown that the interfacial concentration of oxygen is varied with the process, so the oxygen transfer can be considered as a non-equilibrium process. By this model, the experimental data of some systems had been fitted. The results show that it is in good accordance with the experimental data and that the obtained parameters can explain the experimental phenomena well. In addition, the preliminary discussion on the meaning of parameters and their effect on the kinetics had been made.
