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 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.

Important Notes on Latency of Status data
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
Important Note on Priority Date data
This priority date is an estimated earliest priority date and is purely an estimation. This date should not be taken as legal conclusion. No representations are made as to the accuracy of the date listed. Please consult a legal professional before relying on this date.
