A method and apparatus for removing oxygen from a crude inert gas containing oxygen as a contaminant is disclosed. The inert gas is passed through a reactor containing an oxidizable material. The reactor is then regenerated via a gaseous reducing agent such as hydrogen. The hydrogen can be generated

A method and apparatus for removing oxygen from a crude inert gas containing oxygen as a contaminant is disclosed. The inert gas is passed through a reactor containing an oxidizable material. The reactor is then regenerated via a gaseous reducing agent such as hydrogen. The hydrogen can be generated on site via water or steam hydrolysis.

A method of removing O2 from a crude inert gas comprising: contacting said O2 containing inert gas with a material consisting essentially of an inorganic oxidizable material under oxidizing conditions to react said O2 with said oxidizable material to produce an O2-free inert gas and an oxidized mate

A method of removing O2 from a crude inert gas comprising: contacting said O2 containing inert gas with a material consisting essentially of an inorganic oxidizable material under oxidizing conditions to react said O2 with said oxidizable material to produce an O2-free inert gas and an oxidized material, said crude inert gas having O2 concentration up to about 5%; recovering said O2-free inert gas; and contacting said oxidized material with a reducing gas under reducing conditions at temperatures in excess of about 300°C. to convert said oxidized material to said oxidizable material.
