Abstract

See full text

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 1 comprises an exhaust gas supply path 11 supplying a gas exhausted from a nitride compound production device 2, a hydrogen recycle means 10 and a hydrogen supply path 12. The hydrogen recycle means 10 of the hydrogen recycle system 1 is characterized by comprising: a plasma reaction vessel 31 that defines at least a part of a discharge space 32; a hydrogen separation membrane 34 that divides the discharge space 32 from a hydrogen flow path 33 communicated with the hydrogen supply path 12, defines at least a part of the discharge space 32 by one surface thereof and also defines at least a part of the hydrogen flow path 33 by the other surface thereof; an electrode 35 that is disposed outside the discharge space 32; and an adsorbent 36 that is filled in the discharge space 32 and adsorbs the supplied exhaust gas.
