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。
2
The difference of gas diffusion regularity between moving bed and fixed bed enlarged with the increase of catalyst recycle intensity.
随着催化剂循环强度的增加，移动床与固定床在气体扩散规律上的偏离程度增大。

The catalyst was prepared by impregnating depositing process and the catalyst activity was evaluated with a continuous flow fixed bed reactor.
