根据实验室数据对醋酸乙酯加氢制乙醇宏观动力学方程进行参数估计，得到宏观动力学模型。根据动力学模型，同时考虑内扩散的影响以及物料、热量和动量衡算方程建立了醋酸乙酯加氢制乙醇固定床反应器的一维拟均相模型，并分别得到不同氢酯比、不同控制温度、不同压力下的多种工况的模拟结果。模拟结果与实际生产数据吻合。该模型可用于指导工业反应器的设计和操作优化。

A kinetic model of synthesizing ethanol by hydrogenation of ethyl acetate was developed based on laboratory data, and then corrected by taking into consideration the pore diffusion effect. With the correction, the results could conform with actual operation. Based on the principles of material balance, energy balance, momentum balance and kinetics of the reactions, an one-dimensional pseudo-homogeneous model of the ethanol synthesis reactor by hydrogenation of ethyl acetate using fixed bed was established. The simulation results of a variety of conditions were obtained by the model with different H2/EA molar ratios, different temperatures and different pressures. The model could reflect the performance of the hydrogenation reactor and provide guidance for the design and operation optimization of industrial reactor.
