Abstract
Shift conversion of hydrogen-rich reformed gas produced by reaction including partial oxidation of feed gas in a reforming reaction section ( ) is made by its water gas shift reaction with shift conversion catalyst in a shift reaction section ( ) in order to reduce CO contained in the reformed gas and enhance the yield of hydrogen. In this case, for the purpose of enabling high-temperature reformed gas from the reforming reaction section ( ) to undergo the shift conversion as it is and thereby simplifying the construction of a shift conversion unit, the reformed gas from the reforming reaction section ( ) is introduced directly into a reformed gas passage ( ) of the shift reaction section ( ) and thereby undergoes the shift reaction while heat-exchanging with the feed gas.
