Abstract:	Institute of Nuclear Energy Research (INER) has successfully developed a commercial-scale ethanol reforming system, which converts ethanol into hydrogen-rich gases, via autothermal reaction mechanism. In this study, four kinds of noble metal catalyst were extensively investigated with the ethanol reforming system. Two of the four catalysts, Pt-Pd-Rh/gamma-Al(2)O(3) and Rh/gamma-Al(2)O(3)-CeO(2)-ZrO(2), had been conducted in a 26-day long-time test. The Pt-Pd-Rh/gamma-Al(2)O(3) catalyst showed high catalytic activity and achieved an ethanol conversion of 97% in the early stage; but deactivated with reaction time and finally achieved a conversion of only 50% at 26(th) day. The Rh/gamma-Al(2)O(3)-CeO(2)-ZrO(2) catalyst achieved and maintained high ethanol conversion for the first 16 days, then gradually decreased and achieved a conversion efficiency of 85% at 26(th) day.
