ABSTRACT:
A method for removing carbon oxides from a hydrogen stream containing more than 0.1 ppmv of carbon monoxide, carbon dioxide or a mixture thereof, by charging the hydrogen with a hydrocarbonaceous stream containing a minor amount of aromatics to an aromatics saturation zone; saturating at least a portion of the aromatics and methanating at least a major portion of the carbon oxide to produce a reduced aromatics content hydrocarbonaceous stream and a reduced carbon oxide content hydrogen stream; and recovering the reduced aromatics content hydrocarbonaceous stream and the reduced carbon oxide content hydrogen stream. The hydrogen may optionally be dried or further purified.
