| 摘 要： | 在SHBWR汽液平衡方程、幂函数型动力学方程的基础上，假定每个催化床层为－全混流反应器，建立了碳三催化蒸馏选择加氢数学模型，利用二阶P－K算法进行收敛计算。提出了给反应速率方程添加收敛引子，结合“向上逐层累加”法使模型收敛的方案。

| Abstract: | A mathematical model was established for the process of selective hydrogenation of C 3 streams using catalytic distillation technology. SHBWR equation was applied to describe the liquid vapor behavior, and a totally mixed reactor assumption was made to define the reaction occurring in each catalyst bed. A cause leading to the failure of convergence in the simulation was pointed out and a corresponding technique was proposed to improve the convergence. Calculation results agreed well with the experimental data. |
