Abstract:
A shift conversion catalyst layer is divided into at least two front and back stages. A first catalyst and a second catalyst are provided on the upstream side and the downstream side, respectively. The first catalyst has a property that a carbon monoxide conversion rate decreases with an increase in carbon dioxide concentration in a supplied reaction gas at a constant carbon monoxide concentration in the supplied reaction gas and a constant reaction temperature. The first catalyst is combined with the second catalyst such that the degree of decrease in carbon monoxide conversion rate with respect to an increase in carbon dioxide concentration in the supplied reaction gas in the second catalyst is lower than that in the first catalyst. Whereby, the conversion rate of a carbon monoxide concentration of a carbon monoxide shift conversion apparatus can be improved without increasing the used amount of a shift conversion catalyst.

Claim (Index 7):
The method of carbon monoxide shift conversion according to  claim 1 , wherein\n when catalysts and the first catalyst stage and the second catalyst stage have a same composition and a same structure, respective reaction temperatures of the catalyst in the first catalyst stage and the second catalyst stage are controlled independently from each other so that the degree of decrease in carbon monoxide conversion rate with respect to an increase in carbon dioxide concentration in the supplied reaction gas in the case of the second catalyst stage is lower than the degree of decrease in carbon monoxide conversion rate with respect to an increase in carbon dioxide concentration in the supplied reaction gas in the case of the first catalyst stage.
