Method for removing carbon monoxide from reformed gas
First Claim
1. A method for removing carbon monoxide from a reformed gas said method comprising the steps of providing a reformed gas containing hydrogen, carbon dioxide, carbon monoxide and water, treating the reformed gas by subjecting said gas to a hydrogen purifier to reduce the concentration of carbon dioxide, carbon monoxide and water thereby decreasing the ratio of the concentration of components other than hydrogen to the concentration of hydrogen and then converting the carbon monoxide contained in the treated gas into a gas other than carbon monoxide.

Abstract
A method for removing CO from a reformed gas includes the steps of treating the reformed gas by a hydrogen purifier to decrease a ratio of the concentration of components other than hydrogen to the concentration of hydrogen so that the ratio may be lower than in the reformed gas, and then converting CO contained in the gas treated by the hydrogen purifier into a gas other than CO. CO can be removed from the reformed gas, and simultaneously high-purity hydrogen can also be obtained, which leads to the increase of a fuel efficiency and the inhibition effect of performance deterioration.
