ABSTRACT:
The present invention is directed to a process for removing minor amounts of oxygen from inert gas streams to result in very low levels of oxygen contamination in such inert gas streams, wherein the oxygen is removed by the action of stoichiometric quantities of methanol, which react with the oxygen over a catalyst at ambient feed temperature conditions without a requirement for external heating of the reaction.
