Oxidation ：MnAOB+O2——MnXOY
Vatting：MnXOY+H2——MnAOB+H2O
Taking metal manganese had oxidize characteristic, through deoxidize to complete Nitrogen gas oxygen or hydrogen Impurity eliminating, then it will be absorb machine to eliminate water, to get high purity Nitrogen. Manganese Is the key part during the whole eliminating Oxygen,Manganese oxygen oxidize include palladium etc noble metal, It will act as catalyzator during the whole process, to make sure deeply eliminate oxygen, hydrogen under the lower temperature.
