Abstract
The new hydrogen-recovering device has a box-shaped frame made of stainless steel having a takeout pipe attached to its one side. A plurality of spacers are arranged inside the box-shaped frame along a lengthwise direction of the device . A perforated metal plate is fixed to each surface of the box-shaped frame , and a hydrogen-permeating membrane cladded with a membrane holder is further fixed to the perforated metal plate . Hydrogen gas as a decomposition product of hydrocarbon selectively passes through the hydrogen-permeating membrane and flows through the takeout pipe 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 is light and strong, so that it is installed in a gas-reforming plant without use of a fixing jig.
