A method and apparatus for selectively oxidizing the carbon monoxide present in a mixture of gases including hydrogen, to carbon dioxide is disclosed. Oxygen or an oxygen-containing gas mixture is introduced at locations along the latter portion of the reaction chamber in an isothermal reactor to selectively oxidize the carbon monoxide to carbon dioxide and to suppress the reverse water-shift reaction, which produces carbon monoxide and water from carbon dioxide and hydrogen.

Why it's free to use
- Filed October 6, 1993 and granted April 14, 1998. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended October 6, 2013.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by October 6, 2015.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
