摘要： A process for removing methane or oxygen from gases containing the same comprises adding to the gas an amount of oxygen or methane, respectively, which is sufficient to provide, together with any oxygen or methane already present, a stoichiometric excess over the impurity to be removed, and contacting the resulting gas mixture with a catalyst comprising one or more of the metals platinum, palladium, osmium, iridium, ruthenium, rhodium, or silver, to effect combustion and thereby remove the impurity. Quantitative removal of either methane or oxygen from nitrogen, argon, helium, neon, carbon dioxide, and mixtures of any of them, may be effected. The catalytic metal may be in the form of granules, pellets, or powder, may be supported on activated alumina, silica gel, silica, or diatomaceous earth, and may constitute 0,05 to 5% by weight of the total catalyst composition. Natural gas may be used as a source of methane. The reaction pressure may be atmospheric to 500 p.s.i.g., and ignition temperatures as low as 271 DEG C. may be obtained for the methane-oxygen reaction. Specification 879,209 is referred to.
