Title:
FUEL REFORMING SYSTEM
Document Type and Number:
Japanese Patent JP2008247735
Kind Code:
A
Abstract:

To reduce CO concentration while operating stably for a long term.

The fuel reforming system comprises providing at least a reforming reactor 1 and a CO selective oxidation reactor 2, wherein the reactor produces a reformed gas by reacting a raw fuel gas with steam and/or air under the coexistence of a reforming catalyst and the reactor produces a hydrogen rich gas converting into CO2 by selectively oxidizing CO in the reformed gas produced in the reforming reactor 1 under the coexistence of a CO selective oxidation catalyst. A steam condensing separation means 3 which condenses and separates steam contained in the reformed gas before feeding into the CO selective oxidation reactor 2 is provided between the reforming reactor 1 and the CO selective oxidation reactor 2. Steam is condensed and separated from the reforming gas which feeds into the CO selective oxidation reactor 2.
