Based on analyzing the catalytic distillation process of methyl acetate hydrolysis, a physical model of experimental tower is built. The physical model reasonably simplifies the complex process, so that a mathematical model system is built by combining the equilibrium stage model and the fixed-bed model. Its corresponding calculation method is also developed. Using this established model system to simulate three types of column with each has two work modes; the simulated results are in good agreement with results from the experiment. The model system is proved to be applicable and veracious, which can be used to supply reliable data for technical process scale-up and optimization.
