采用不锈钢微通道板叠层粘接的方法组装单元反应器，包括燃料蒸发器、换热器、催化燃烧器和蒸汽重整器，开发了集成式微通道甲醇处理器。将市售的Cu/ZnO/Al 2 O3催化剂涂覆在单元反应器的微通道内用于水蒸气重整。采用“初湿法”制备Pt/Al_2O_3催化剂颗粒，并将其装入空腔反应器中进行催化燃烧实验。这些单元反应器被集成开发燃料处理器，并在不同的反应条件下操作，以优化反应器的性能，包括甲醇蒸汽重整器和甲醇催化燃烧器。优化后的燃料处理器尺寸为60 mm × 40 mm × 30 mm，在230-260°C下可产生450 sccm的H2、CO2和CO含量分别为73.3%，24.5%，2.2%，59 Wt的重整气。
An integrated microchannel methanol processor was developed by assembling unit reactors, which were fabricated by stacking and bonding microchannel patterned stainless steel plates, including fuel vaporizer, heat exchanger, catalytic combustor and steam reformer. Commercially available Cu/ZnO/Al2O3catalyst was coated inside the microchannel of the unit reactor for steam reforming. Pt/Al2O3pellets prepared by ‘incipient wetness’ were filled in the cavity reactor for catalytic combustion. Those unit reactors were integrated to develop the fuel processor and operated at different reaction conditions to optimize the reactor performance, including methanol steam reformer and methanol catalytic combustor. The optimized fuel processor has the dimensions of 60mm×40mm×30mm, and produced 450sccm reformed gas containing 73.3% H2, 24.5% CO2and 2.2% CO at 230–260°C which can produce power output of 59Wt.
