甲醇重整制氢具有多方面的优势，是制取氢气的重要途径。传统固定床反应器受到传热传质的限制，导致床层中颗粒催化剂的效率降低。本文设计了一种微型板式反应器，开展了固定床催化剂在床层中不同分布形式对甲醇蒸气重整制氢反应性能影响的研究。结果表明，催化剂床层中沿反应物流动方向上的温度分布出现了冷点温差。通过催化剂合理分布可以降低冷点温差并可提高甲醇蒸气重整反应的氢气产量。在最佳催化剂分布条件下获得了微反应器轴向最小冷点温差的温度分布，其甲醇转化率和氢气产率也较高。

Methanol reforming is a promising candidate of hydrogen producting method with advantages in many ways. Conventional reformers with packed bed catalyst are usually limited by heat and mass transfer,leading to low catalyst effectiveness of the conventional pellet. In this work,a micro plate-type reactor was developed to investigate the influence of catalyst activity distribution on methanol steam reforming. Results show that cold spot temperature differences were observed in the temperature profile along the flow of the reactants in micro-reactor. It was experimen-tally verified that decreasing cold spot temperature differences improves hydrogen production. The minimum cold spot temperature difference was observed in the optimal catalyst distribution. It is shown that the optimal catalyst distribu-tion is superior in methanol conversion and H2 production rate.
