REMOVING OF OXYGEN FROM INNERT GAS

摘要

PURPOSE:To simply remove the oxygen mixed in the inert gas at low temp., by utilizing a catalytic oxidation added with methanol or carbon monoxide. CONSTITUTION:The oxygen mixed in the inert gas is transformed to carbon monoxide and/or carbon dioxide by adding methanol or carbon monoxide and allowing to cause the catalytic oxidation and then removed by absorption. The catalytic oxidation of the methanol with oxygen is carried at about the ordinary temp. -200 deg.C in the presence of a palladium-base catalyst or platinum- base catalyst. Then the catalytic oxidation of carbon monoxide with oxygen is carried at about the ordinary temp. -400 deg.C in the presence of the platinum- base catalyst, copper-base catalyst or palladium-base catalyst.
