KINETIC ANALYSIS ON NON-EQUILIBRIUM PROCESS OF OXYGEN TRANSFER AT INTERFACE

Divided into two steps of a chemical reaction and a mass transfer process,the interracial 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.
