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 150–300 hr-1 while heating the reactor to evenly raise the temperature of the deoxidizer to 420–450℃, and hold at this temperature for 1 hour.
Introduce a nitrogen-hydrogen mixture containing 10–20% hydrogen at a space velocity of 150–300 hr-1. 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. Stop heating, turn off the hydrogen while retaining a small flow of nitrogen, and purge the system appropriately. The deoxygenation operation can then begin immediately. If the system is to be placed on standby, allow it to cool naturally while maintaining a small flow of nitrogen. When the temperature inside the tower approaches room temperature, close the nitrogen supply and the vent valve, and keep on standby.
● 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. Refer to the activation steps described above for the regeneration procedure.
※ 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.
