Abstract
The present invention comprises a method for lowering the carbon monoxide content of a CO-containing hydrogen rich gas stream by contacting the gas stream with an adsorbent capable of preferentially adsorbing the carbon monoxide in the gas stream, the adsorbent being selected from the group consisting of platinum, palladium, ruthenium, rhenium, iridium, the carbides and nitrides of tungsten, molybdenum, vanadium, chromium, tantalum, and mixtures thereof whereby a substantially CO free, hydrogen rich gas stream is obtained. Preferably the absorbent will have a surface area from 0.5 to about 200 m.sup.2 /gm.
