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 a scavenger capable of preferentially oxidizing the carbon monoxide in the gas stream and then regenerating the scavenger. The scavenger is selected from the group of mixed oxides of manganese and copper; mixed oxides of manganese and copper in combination with mixed oxides of silver, nickel, iron, and tin; mixed oxides of tin and copper; SnO.sub.2 --CuO gels; and mixtures thereof. Preferably the scavenger will have a surface area from about 0.5 to about 200 m.sup.2 /gm.
