Abstract: The catalytic properties of CuO-CeO 2 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 2 /γ-Al 2 O 3 catalyst provided complete DMM conversion and hydrogen productivity > 10 L h −1 g cat −1 at 280 °C, GHSV (gas hourly space velocity) = 15,000 h −1 and DMM:O 2 :H 2 O:N 2 = 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.
