摘要： A ferritic stainless steel sheet containing 16-25 mass % of Cr and Ti and/or Nb at a ratio of (C+N) × 8 or more is used as a substrate for formation of a hydrogen-permeating membrane exposed to a high-temperature, atmosphere of 600-900°C, while another ferritic stainless steel sheet containing Cr up to 15 mass % is used as a substrate for formation of a hydrogen-permeating membrane exposed to a high-temperature atmosphere of 450-600°C. The stainless steel sheet is formed to a perforated body 3a with holes for passage of gas. A hydrogen-permeating membrane 3b is fixed to an external surface of the perforated body 3a to build up a hydrogen-separating pipe 3. A plurality of the hydrogen-separators 3 are inserted into a cavity between inner and outer walls of a double-pipe 2 filled with a catalyst 4. Hydrocarbon gas fed through a nozzle 7 is decomposed with combustion heat of a fuel F fed into an inner space of the double-pipe 2. A decomposition product H 2 selectively permeates through the membrane 3b and flows out through the takeout opening 8.

摘要： 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.
