ヘリウム液化システムで使用した水素除去剤の再生

抄録

In recent years, liquid-helium supply and recovery systems have shown serious problems with hydrogen impurities in the system. To remove hydrogen impurities, we developed a hydrogen removal apparatus and installed our system. In this apparatus, silver-zeolite “Ag400” was used as the hydrogen adsorbent. Previously, Ag400 could not be regenerated after hydrogen absorption. However, we have found a new regeneration method for Ag400. In this paper, we report this regeneration method and consider the regeneration mechanism.
