| 摘 要： | 建立了绝热式氨合成塔的二维非均相数学模型,考察了由硫化氢引起的催化剂中毒对整个床层状态的影响。应用正交配置法及龙格-库塔方法对方程进行求解,获得了床层温度、氨浓度随催化剂中毒深度的变化规律。针对中毒物不同浓度,讨论了床层中各组分及温度所受到的影响和变化。

| Abstract: | Two-dimension non-uniform phrases mathematics modei of adiabatic reactor of synthetic Ammonia was established in the paper. The whole reactor' s state was studied while catalyst was poisoned by H2S. The equations were solved by methods of collocation and Runge-Kutta. The conclusions that temperature of adiabatic reactor of synthetic Ammonia and concentration of each reactant varied with height of reactor were taken. The effect that temperature of adiabatic reactor of synthetic Ammonia and concentration of each reactant changed with concentration of H2S also was studied. |
