Instructions for Use：
● Activation Before Use
Load the deoxidizer into the reactor, and purge the air from the system with an inert gas.Introduce pure nitrogen or other inert gas at a space velocity of 150–300hr-1 while heating the reactor to evenly raise the temperature of the deoxidizer to 180–250℃. For industrial processes, it is necessary to hold at this temperature for an appropriate period to ensure relatively uniform temperature distribution within the tower.
For industrial use, introduce a nitrogen-hydrogen mixture containing 10–20% hydrogen at a space velocity of 150–300hr-1 . For laboratory-scale applications, pure hydrogen may be used for activation and regeneration. Due to the temperature rise and the introduction of hydrogen, water vapor will be discharged from the vent outlet. The activation reaction proceeds layer by layer along the direction of gas flow. When the activation front moves from one end to the other, and no water vapor is detected in the vented exhaust gas, the activation is essentially complete. Turn off the hydrogen while retaining the nitrogen, and purge the system appropriately. The system can be used immediately at this temperature, or it can be cooled down and sealed for standby use.
● Deoxygenation Purification
After activation is completed, the gas to be purified can be introduced at any time, and the deoxidizer will begin deoxygenation operation.
● Deoxidizer Regeneration
After the deoxidizer becomes saturated with oxygen, it must be switched to regeneration mode. Follow the same procedure as the activation steps described above.
※ Note:
1. The top layer inside the deoxygenation tower shall be covered with inert ceramic balls approximately 20cm thick, spread evenly.
2. The gas flows through the deoxygenation tower from top to bottom.
