Patent number: 6814944Abstract: Shift conversion of hydrogen-rich reformed gas produced by reaction including partial oxidation of feed gas in a reforming reaction section (6) is made by its water gas shift reaction with shift conversion catalyst in a shift reaction section (10) 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 (6) 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 (6) is introduced directly into a reformed gas passage (11) of the shift reaction section (10) and thereby undergoes the shift reaction while heat-exchanging with the feed gas.Type: GrantFiled: August 28, 2001Date of Patent: November 9, 2004Assignee: Daikin Industries, Ltd.Inventors: Nobuki Matsui, Shuji Ikegami, Yasunori Okamoto, Kazuo Yonemoto
