Resumo

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/(g_cat 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/(g_cat h).
