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).

燃料电池供应用 CuO-CeO2/γ-Al2O3 催化剂上二甲醚低温部分氧化成富氢气体

CuO-CeO2/γ-Al2O3 体系作为催化剂用空气部分氧化二甲醚 (DME) 以产生用于燃料电池供给的富氢气体具有良好的前景。在大气压、~350°C 的温度和 7 L/(gcat h) 的反应混合物流速和 DME:O2:N2 摩尔比为 1:1:4(DME:空气 = 1:5)下,催化剂将 DME 完全转化为富氢气体,CH4 含量低(≤0.8 mol%),H2 产率约为 3.1 L/(gcat h)。
