Abstract
A degree of micro-mixing with a clear physical meaning is introduced to construct a universal reaction model which is applicable to reactions of any order. The model was applied to the multi-nozzle mixing system with two kinds of reaction system, CO2-NH3 and CO2-NaOH, and was proved to explain the experimental results fairly well. The model was further applied to the batch tank reactor with alkaline hydrolysis of ethyl acetate. Also in this case, the trial was successful to some extent though some simplification was made during its course.
