Abstract
A process for reducing free oxygen in a gaseous nitrogen stream includes the steps of (i) reforming a hydrocarbon to generate a gas mixture containing hydrogen and carbon oxides, (ii) mixing the gas mixture with a nitrogen stream containing free oxygen, and (iii) passing the resulting nitrogen gas mixture over a conversion catalyst that converts at least a portion of the free oxygen present in the nitrogen to steam wherein the hydrocarbon reforming step includes oxidation of a hydrocarbon using an oxygen-containing gas.
