The methanol reforming microreactor has the advantages of small size, high efficiency, and high safety and is one of the main ways of online hydrogen production. Considering the catalyst of traditional microchannel reactors falloff quite easily, this study designs and manufactures a microchannel with a secondary structure to address this problem. First, the base structure of the microchannel was processed by wire cut electrical discharge machining (WEDM), and then a reticulated secondary structure having a depth of 30 μm and a width of 50 μm was processed on the substrate of the microchannel by laser beam machining (LBM). In this study, the catalyst loading strength of the microchannel with a secondary structure was tested, and the influence of the secondary structure on the static performance of the catalyst was studied. Finally, hydrogen production experiments were carried out on microchannels with a secondary structure, and the influence of the secondary structure on hydrogen production performance and hydrogen production stability at different flow rates and temperatures was determined.

甲醇重整微反应器多尺度微通道处理及制氢性能

甲醇重整微反应器具有体积小、效率高、安全性高等优点，是在线制氢的主要方式之一。考虑到传统微通道反应器的催化剂很容易脱落，本研究设计并制造了一种具有二级结构的微通道来解决这个问题。首先，通过线切割电火花加工（WEDM）加工微通道的基础结构，然后通过激光束加工在微通道的基板上加工出深度为30μm，宽度为50μm的网状二级结构(LBM)。本研究测试了具有二级结构的微通道的催化剂负载强度，研究了二级结构对催化剂静态性能的影响。最后，
