微反应器是利用精密加工技术制造出的通道特征尺寸在1～1 000 μm之间的微型反应器.由于拥有微小的通道尺寸和极大的比表面积,微反应器具有优异的传热传质能力和很好的防爆安全性,可以实现物料的瞬间均匀混合、高效的热能传导以及反应参数的精确控制,近年来在甲醇重整制氢反应等领域中应用前景广阔.本文首先介绍甲醇重整制氢微反应器的系统组成和运行原理,接着重点围绕甲醇重整制氢微反应器的结构设计、加工技术、供热模式等进行分析,同时对其现有的和潜在的应用场景等方面进行介绍,最后对其未来的发展趋势进行预测与展望.

The microchannel reactor is characterized with microchannels of 1-1 000 μm in diameter and is manufactured by precision processing technology.Due to the smallness of channel sizes and the diversity of channel types,this reactor secures excellent heat and mass transfer capacities and high degree of safety.In addition,it can achieve instant uniform mixing of materials and efficient heat transfer.These advantages facilitate the broad application of the microchannel reactor to methanol-reforming reactions to produce hydrogen.In this article,the methanol steam reforming microreactor from system composition,operating principle,design and manufacturing,and applications are reviewed.Finally,the future development trend of methanol steam reforming microreactors is predicted.
