摘要：

The properties of supported Pt-containing granular (Pt/Ce0.75Zr0.25O2 - delta) and structured catalysts (Pt/Ce0.75Zr0.25O2 - delta/eta-Al2O3/FeCrAl) in methanol decomposition to synthesis gas for feeding solid oxide fuel cells have been studied. It has been shown that the use of a structured catalyst for the methanol decomposition reaction is promising. It has been found that the addition of a small amount of oxygen to the feed mixture hinders the formation of carbon and thereby increases the on-stream stability of the catalyst. At atmospheric pressure, a temperature of approximate to 400 degrees C, a reaction mixture feed space velocity of 5.6 L/(g(cat) h), and a CH3OH : air volume ratio of 1, the proposed 0.15 wt % Pt/8 wt % Ce0.75Zr0.25O2 - delta/6 wt % eta-Al2O3/FeCrAl structured catalyst can provide a complete methanol conversion to synthesis gas with a total content of H-2 and CO of approximate to 64 vol % and a productivity with respect to synthesis gas of approximate to 6.7 L(H-2 + CO)/(g(cat) h).
