摘 要: | 建立了二维稳态多组分传输反应的模型,对平板微反应器中Rh催化剂涂层上甲烷-干、湿空气催化重整制合成气进行了数值计算,并分析了采用湿空气时反应通道长度和高度对重整性能的影响.结果表明:进口速度低于2 m/s时,采用湿空气可提高甲烷转化率和产氢率,反应器出口的温度降低以及减少积碳的发生;采用湿空气时,反应通道长度增大,甲烷的转化率提高,出口氢气含量增大,出口温度相应地降低;反应通道高度增大,甲烷的转化率降低,出口氢气的含量减少,出口温度升高.

Abstract: | A two dimensional,steady-state,multi-component transport and reaction model was established for methane catalytic reforming with dry/wet air in a plate micro-reactor.The effect of the channel length and height on the reaction performance was discussed.Calculation results show that methane-wet air catalytic reforming can obtain higher methane conversion ratio and hydrogen output at inlet velocity of lower than 2 m/s,and the lower reactor outlet temperature、reduced carbon deposit in the reactor are also obtained;What is more,with a longer reaction channel a higher methane conversion is reached,higher hydrogen output and lower temperature of reactor outlet are also achieved;with a higher reaction channel,a lower methane conversion and lower hydrogen output and higher temperature of reactor outlet are resulted. |
