【Abstract】 A stable convergence calculation method using Newton homotopy continuation method based on the non-equilibrium rate model is established. It is applied to simulate the catalytic distillation process for hydrolysis of the azeotrope of methyl acetate and methanol. And the influence of the mole ratio of water to methyl acetate in feed, space velocity and the ratio of reflux to feed on conversion of methyl acetate is investigated. The agreement of calculated results with the experimental data is satisfactory.更多还原
