ABSTRACT:
An argon gas stream containing hydrogen, carbon monoxide, water vapor, oxygen carbon dioxide, nitrogen and methane is purified by drying the gas stream with a desiccant, oxidizing the hydrogen and carbon dioxide to water vapor and carbon dioxide by contact with oxidizing catalysts in the presence of excess oxygen, removing the water vapor and carbon dioxide from the gas stream by adsorption, removing excess oxygen by chemisorption at elevated temperature and removing the nitrogen and methane by adsorption at cryogenic temperature. Alternatively, excess oxygen is removed from the gas stream by adsorption at a cryogenic temperature.
