Abstract

An improved method and apparatus for regeneration and reuse of He-N2-CO2 mixed gas for carbon dioxide gas laser generator. The mixed gas after use is contacted with a precious metal catalyst (for example, Pt-Al2O3) at a temperature of 200 - 300 °C to react CO and O2 so as to form CO2. Poisoning of the catalyst by NO x is suppressed at this relatively high temperature of reaction.
Deterioration of the catalyst can be prevented to some extent by pretreating the catalyst prior to use, and the activity of the catalyst, even if decreased, may be recovered by reactivation.
