    • Apparatus and method for converting hydrocarbon fuels to hydrogen-rich reformate that incorporate a carbon dioxide fixing mechanism into the initial hydrocarbon conversion process. The mechanism utilizes a carbon dioxide fixing material within the reforming catalyst bed to remove carbon dioxide from the reformate product. The bed optionally contains a water gas shift catalyst. The removal of carbon dioxide from the product stream shifts the reforming reaction and shift reaction equilibria toward production of higher concentrations of hydrogen with only small amounts of carbon oxides produced. The carbon oxide-depleted reformate is directed to a purification bed comprising a hydrogen fixing material that removes hydrogen from the reformate stream to provide fixed hydrogen and a hydrogen-depleted reformate that flows out of the purification bed. The purification bed is heated to release fixed hydrogen from the hydrogen fixing material to provide a highly pure hydrogen gas.
    • 将碳氢化合物燃料转化为富含氢的重整产物的装置和方法,其将二氧化碳固定机构并入初始烃转化过程。 该机构利用重整催化剂床内的二氧化碳固定材料从重整产品中除去二氧化碳。 该床任选地含有水煤气变换催化剂。 从产物流中除去二氧化碳使重整反应和转化反应平衡转向生产较高浓度的氢气,只产生少量的碳氧化物。 不含氧化碳的重整产品涉及一种净化床,该纯化床包含从重整产品流中除去氢气以提供固定氢气的氢固定材料,以及从净化床流出的贫氢重整产品。 净化床被加热以从氢固定材料释放固定的氢气以提供高纯度的氢气。
