With the increase of coal mine methane superficie velocity, pressure loss and outlet temperature of the oxidationbed increase.
随着进入氧化床的乏风气体表观速度的增加，压强损失和出口温度都增加；

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。
