| 摘 要： | 以CO加氢和CO_2加氢合成甲醇平行反应为独立反应,甲醇和CO_2为关键组分,建立了鲁奇副产蒸汽管壳型甲醇合成塔催化床的二维数学模型,用二维正交配置法求得催化床内各组分浓度和床层温度随轴向和径向分布。比较了二维正交配置法及差分解法求解结果和所化机时,并讨论了配置点数对计算结果和所化机时的影响。模拟计算表明,配置点数取4的二维正交配置法是较为理想的求解方法。

| Abstract: | Two-dimensional mathematical model of Lurgi tube-shell type methanol synthesis reactor with by-product steam was established, with taking hydrogenation of CO and CO_2 as the independent reactions and methanol and CO_2 as the key components in the methanol synthesis system. The concentrations and temperature profiles in axial and radial direction inside the reaction tubes were obtained by two-dimensional orthogonal collocation method. This method was comparied with finite difference method. The former is better than the later for solving the partial differential equations. |
