在微通道反应器内通过重整反应制氢，可以有效避免燃料电池的储氢问题。与传统的平行微通道结构相比，网状微通道属于一种互连结构，因其单位反应面积较大、堵塞问题较少、催化剂更容易更换和再生而逐渐得到应用。在这项工作中，开发了一种用于甲醇蒸汽重整的网状微通道反应器。通过对比实验研究不同反应条件下微通道截面和分布对反应性能的影响。实验结果表明，采用网状齿形微通道板的反应器性能优于采用网状矩形微通道板的反应器。网状微通道和矩形微通道的前向密集分布和后向稀疏分布(DFSB)均比网状微通道的前后方向等分布(EFB)和前向稀疏分布和后向密集分布(SFDB)表现出更好的性能。版权所有 (c) 2015，Hydrogen Energy Publications, LLC。由爱思唯尔有限公司出版。保留所有权利。
Producing hydrogen inside microchannel reactor by reforming reaction can effectively avoid the problem of hydrogen storage for fuel cell. Compared with conventional parallel microchannel structure, mesh microchannel belongs to a kind of interconnected structure, which has been gradually applied due to its larger unit reaction area, less plugging problem, easier change and regeneration of catalyst. In this work, a mesh microchannel reactor for methanol steam reforming is developed. Comparative experiments are conducted to investigate the effects of microchannel cross-section and distribution on reaction performances under different reaction conditions. Experiment results indicate that the performance of reactor with mesh tooth microchannel plate is better than that with mesh rectangular microchannel plate. Dense-distribution in the Front direction and Sparse distribution in the Back direction (DFSB) of both mesh tooth and rectangular micro channels present better performances than Equal-distribution in the Front-Back direction (EFB) and Sparse-distribution in the Front direction and Dense-distribution in the Back direction (SFDB) of mesh microchannels.
