【Abstract】 Reaction and mass transfer are studied using thin film experiment, the model of reaction kinetics and the equation of mass transfer rate are established on the basis of experiments.The laws of fluid flow,mixing,film forming ,surface renewal and mass transfer are studied using three different size disc-rotating reactor in cold model flow experiments.Combining the results of reaction and reactor,the model of PET polycondensation process in disc-rotating reactor is built,it can be applied to industrial process well.The effects of operation variables on PET polycondensation process are simulated.更多还原
