Abstract

To represent the macro-mixing rate process in a batch reactor, a combined model of the extremes for mixing is proposed by extending the treatment of Miyawaki''s model. This model is characterized by the segregation function and has the simplest mixing structure: that composed of both complete segregation and perfect mixing. By equating the intensity of segregation derived for the proposed model to that for the batch mass exchange-type model, the model parameter can be related as a function of macro-mixing time with the mixing parameter of the mass exchangetype model. This treatment of the model is experimentally confirmed by using three kinds of reactions having different rate constants. The mixing parameter of this model calculated from the experimental data of irreversible second-order reactions with different rate constants in a wide range of operational conditions is more successfully correlated to the Reynolds number of the reaction system. Further, the overall reaction performance is found to be characterized by a dimensionless number which is given from both the reaction rate and the mixing parameter.
