| Summary: | The catalytic properties of CuO-CeO<sub>2</sub> supported on alumina for the oxidative steam reforming (OSR) of dimethoxymethane (DMM) to hydrogen-rich gas in a tubular fixed bed reactor were studied. The CuO-CeO<sub>2</sub>/γ-Al<sub>2</sub>O<sub>3</sub> catalyst provided complete DMM conversion and hydrogen productivity > 10 L h<sup>−1</sup> g<sub>cat</sub><sup>−1</sup> at 280 °C, GHSV (gas hourly space velocity) = 15,000 h<sup>−1</sup> and DMM:O<sub>2</sub>:H<sub>2</sub>O:N<sub>2</sub> = 10:2.5:40:47.5 vol.%. Comparative studies showed that DMM OSR exceeded DMM steam reforming (SR) and DMM partial oxidation (PO) in terms of hydrogen productivity. Thus, the outcomes of lab-scale catalytic experiments show high promise of DMM oxidative steam reforming to produce hydrogen-rich gas for fuel cell feeding.
