Abstract

The CuO–CeO2/γ-Al2O3 systems have good prospects as catalysts for partial oxidation of dimethyl ether (DME) with air to give hydrogen-rich gas for fuel cell feeding. At atmospheric pressure, temperature of ~350°C, and reaction mixture flow rate of 7 L/(gcat h) and the DME : O2 : N2 molar ratio of 1 : 1 : 4 (DME : air = 1 : 5), the catalysts provide complete DME conversion to hydrogen-rich gas with a low content of CH4 (≤0.8 mol %) and H2 production rate of ~3.1 L/(gcat h).
