Methanol Decomposition to Synthesis Gas over Supported Platinum-Containing Catalysts
Abstract
The properties of supported Pt-containing granular (Pt/Ce0.75Zr0.25O2 – δ) and structured catalysts (Pt/Ce0.75Zr0.25O2 – δ/η-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 ≈400°C, a reaction mixture feed space velocity of 5.6 L/(gcat h), and a CH3OH : air volume ratio of 1, the proposed 0.15 wt % Pt/8 wt % Ce0.75Zr0.25O2 – δ/6 wt % η-Al2O3/FeCrAl structured catalyst can provide a complete methanol conversion to synthesis gas with a total content of H2 and CO of ≈64 vol % and a productivity with respect to synthesis gas of ≈6.7 L(H2 + CO)/(gcat h).
