摘要: 自行研制了一种高效的板式反应器，集预热、气化、重整、催化燃烧反应于一体。在该反应器中进行了一系列甲醇自热重整制氢实验，考察了反应器床层的温度分布及氧醇比、水醇比对甲醇重整制氢过程的影响。实验中重整温度保持在450 ℃～650 ℃，当甲醇的气体空速为4 000 h－1时，产生重整气3 m3/h～5 m3/h(重整气中氢气浓度44.0%～50.0%，CO浓度为10.0%～12.0%，产氢率为1.5m3／kg(CH3OH)，系统处于常压。Abstract: A compact planar reformer for methanol reforming was designed and tested. The advantages of the reformer are that it is very compact, easy to be placed on board and scaled up. The reforming chamber two vaporization chambers, two combustion chambers and four heat exchange chambers are all integrated in one unit as the reformer. The effects of the ratios of O2/methanol and water/methanol on the performance of the reformer were investigated. In addition, the temperature distribution of different chambers in the reformer was studied. When the space velocity of methanol was 4 000 h－1, the gas output of the unit reached 3 m3/h～5 m3/h..
