| 摘 要： | 为了强化微通道中甲醇水蒸气重整制氢,考察了催化表面活性分布对该反应过程的影响。利用计算流体力学软件FLUENT中的通用有限速率模型对微通道中甲醇水蒸气重整进行了二维数值研究。计算表明,在相同的反应条件下,通过微通道壁面上催化活性的合理分布可以提高反应器出口甲醇的转化率,这一效果在低进口温度和高速度下更为明显,在进口温度为453 K、进口速度为1.0 m/s下转化率最大提高46%。合理的活性分布应是进口处活性较低,沿着反应通道活性逐渐增加。这种催化活性分布还可降低反应通道中的冷点温差。

| Abstract: | In order to intensify the process of methanol steam reforming in micro-channel for hydrogen production,the effect of catalytic activity distribution on the reaction was investigated.By using the general finite reaction rate model in CFD software of FLUENT,2-D simulation of this process was studied.The results show that under the same conditions,the methanol conversion rate at the outlet of reactor through reasonable catalytic surface activity distribution on the micro-channel wall can be improved.This effec... |
