The catalyst bed requires periodic regeneration with a stream of hydrogen diluted in hot nitrogen.
该催化剂床层需要定期用热氮中稀释的氢气物流再生。

The nitrogen Deoxo Vessel contains a fixed bed of free copper catalyst which removes oxygen from the nitrogen stream by oxidation of copper to copper oxides.
氮气脱氧罐中装有一个游离铜催化剂的固定床，通过将铜氧化成氧化铜把氧气从氮气中脱除。

Besides, leaching out of catalyst ingredients in inert liquid medium and entraining of small catalyst particles in outlet stream were to some extent responsible for the catalyst deactivation.
