Abstract
Provided are a hydrogen recycle system and a hydrogen recycle method, whereby hydrogen can be purified to high purity at high yield from a gas, said gas being exhausted from a nitride compound production device, and recycled. The hydrogen recycle system comprises an exhaust gas supply path supplying a gas exhausted from a nitride compound production device, a hydrogen recycle means and a hydrogen supply path. The hydrogen recycle means of the hydrogen recycle system is characterized by comprising: a plasma reaction vessel that defines at least a part of a discharge space; a hydrogen separation membrane that divides the discharge space from a hydrogen flow path communicated with the hydrogen supply path, defines at least a part of the discharge space by one surface thereof and also defines at least a part of the hydrogen flow path by the other surface thereof; an electrode that is disposed outside the discharge space; and an adsorbent that is filled in the discharge space and adsorbs the supplied exhaust gas.
