Abstract : The patent describes a method of regenerating a spent atmosphere containing one or more of hydrogen, methane, sulfites, phosphites, carbon monoxide, hydrogen sulfide and heavy hydrocarbons as contaminants. It conprises of subjecting the spent atmsophere to catalytic oxidation to convert hydrogen to water, carbon monoxide to carbon dioxide and methane and other hydrocarbons to carbon dioxide and water; passing the oxidized gas through activated carbon whereby sulfites, sulfides and phosphites are absorbed; passing the resulting gas containing carbon dioxide into contact with a bed of silver oxide to remove the carbon dioxide; desorbing the carbon dioxide and reducing it with carbon by catalytic reduction with hydrogen. This is of interest in submarines, in mines, or in manned space ships.
