Shell粉煤气化制氨工艺中变换反应的分段研究

Stage Research of Shift Reaction in Ammonia Making Process by Shell Pulverized Coal Gasification

采用动力学方程式,针对某厂Shell粉煤加压气化工艺条件,设计了动力学模型,对变换反应的分段问题,特别是第一段反应器反应深度的控制问题进行了研究和讨论;考察了水/气、反应压力和床层热点温度对甲烷化副反应的影响。

By using dynamic equation, in allusion to Shell pulverized coal pressure gasification prccess conditions, dynamic model was designed, the study ＆ discussion were made for stage problem of shift reaction, especially for control problem for reaction depth of first stage reactor; the influence of water/gas ratio, reaction pressure and hot point temperature in bed on by-reaction of methanation was investigated.
