    • The new hydrogen-recovering device 10 has a box-shaped frame 11 made of stainless steel having a takeout pipe 12 attached to its one side. A plurality of spacers 13 are arranged inside the box-shaped frame 11 along a lengthwise direction of the device 10. A perforated metal plate 14 is fixed to each surface of the box-shaped frame 11, and a hydrogen-permeating membrane 16 cladded with a membrane holder 15 is further fixed to the perforated metal plate 14. Hydrogen gas as a decomposition product of hydrocarbon selectively passes through the hydrogen-permeating membrane 16 and flows through the takeout pipe 12 to the outside. A tubular device, which has the structure that a hydrogen-permeable membrane is fixed to a perforated metal plate wound around a tubular frame, is also proposed. The device 10 is light and strong, so that it is installed in a gas-reforming plant without use of a fixing jig.
    • 新的氢气回收装置10具有由不锈钢制成的箱形框架11,其具有连接到其一侧的取出管12。 多个间隔件13沿着装置10的长度方向布置在箱形框架11的内部。多孔金属板14固定在箱形框架11的每个表面上,并且透氢膜16包覆有 膜保持器15进一步固定在穿孔金属板14上。作为烃分解产物的氢气选择性地穿过氢气渗透膜16,并通过取出管12流到外部。 还提出了一种管状装置,其具有将透氢膜固定到缠绕在管状框架上的穿孔金属板的结构。 装置10是轻而坚固的,因此它不需要固定夹具即可安装在气体重整装置中。
