    • Disclosed is a chemical microreactor that provides a means to generate hydrogen fuel from liquid sources such as ammonia, methanol, and butane through steam reforming processes when mixed with an appropriate amount of water. The microreactor contains capillary microchannels with integrated resistive heaters to facilitate the occurrence of catalytic steam reforming reactions. Two distinct embodiment styles are discussed. One embodiment style employs a packed catalyst capillary microchannel and at least one porous membrane. Another embodiment style employs a porous membrane with a large surface area or a porous membrane support structure containing a plurality of porous membranes having a large surface area in the aggregate, i.e., greater than about 1 m2/cm3. Various methods to form packed catalyst capillary microchannels, porous membranes and porous membrane support structures are also disclosed.
    • 公开了一种化学微反应器,其提供了当与适量的水混合时通过蒸汽重整过程从液体源例如氨,甲醇和丁烷产生氢燃料的手段。 微反应器包含具有集成电阻加热器的毛细管微通道,以促进催化蒸汽重整反应的发生。 讨论了两种不同的实施方式。 一种实施方案采用填充催化剂毛细管微通道和至少一种多孔膜。 另一种实施方案采用具有大表面积的多孔膜或多孔膜支撑结构,其包含多个聚集体中具有大表面积的多孔膜,即大于约1m 2 / cm 3。 还公开了形成填充催化剂毛细管微通道,多孔膜和多孔膜支撑结构的各种方法。
