| 摘 要： | 建立了模拟实验室膜反应器的两种数学模型，活塞流模型和多级全混流模型，将实验数据应用于所建模型，在不同的空速，临氢比、吹扫气流速、温度和膜位置等条件下，拟合出丙烷脱氢的表观活化能、指前因子和表观反应级数，计算结果与实验结果相当符合。

| Abstract: | Two kinds of mathematical models have been established for propane dehydrogenation to propene in plug flow and multistage well mixed flow membrane reactor respectively. Apparent activation energy, pre exponential factor and apparent order of the reaction have been estimated according to the models, and the results are in agreement with the experimental data very well for membrane reactor under different conditions, e.g. temperature, space velocity, ratio of propane to hydrogen, purge gas rate, membrane location, etc. The yield of propene has been calculated in membrane reactor with different permeability and permselectivity. This will guide the preparation of inorganic membranes. |
