摘要

1 引言耐硫甲烷化催化剂具有耐硫、抗析炭等特点

可简化甲烷化工艺流程

便于工厂操作。设计合理的工业反应器和延长催化剂使用寿命是目前工业化急需解决的问题。作者对SDM-1型耐硫甲烷化催化剂宏观动力学进行了研究。 2 实验 2.1 测试装置实验流程见图1。反应器为增压内循环无梯度反应器

将直径27mm、高25mm的催化剂筐置于导流环中

筐下方装有调速叶轮

转速1200～7200r/min。用热电偶测量反应床温度。实验用原料气由钢瓶中配制

配制后倒置48h以上

使气体充分混合。原料气经净化器脱除有害杂质后

由质量流量计计量

进入预热器升温至300℃

送反应器

出口气体经分离器至皂膜流量计计量

然后放空

或送HP5890色谱仪分析。动力学测试前通过空白试验证实实验装置无催化活性。当转速为2850r/min

实验范围内消除了外扩散影响。H_2S体积浓度控制在0.09％

Abstract

The macrokinetics of sulfur-tolerant methanation SDM - 1 4φ5×5 mm catalyst under conditions——0. 30-1. 20MPa

573-673K

H251-54%

CO14-25%

CH42.5-14%

CO2 5. 3-9. 0% and N2 10. 2-13. 4% is studied in a gradientless reactor with internal -recycle. The macrokinetics model is as follows rCH4 = l. 3491 ×10-5exp[- 32777/ (RT) ]p0.83yCO0.51yH20.32rCO2=1.7014×10-6exp[-52311/(RT)]p1.56yCO0.50yH2O(1-β)1.60The kinetics equations are tested by mathematical statistic method and residual distribution. The result shows that the model is reasonable.
