摘　　要：分别考察了温度、水醚比和空速对自制的CuMn2O4/Al2O3双功能催化剂性能的影响,研究结果表明:CuMn2O4型催化剂的DME转化率和H2产率始终高于其他两种催化剂;随着水醚比的升高,DME转化率和H2产率先升高后趋于稳定;随着水醚比的升高,CO2的选择性升高,CO的选择性减小;随着空速的升高,DME转化率和H2产率先不变后降低。该研究对车用二甲醚发动机在线燃料设计具有重要的意义。The effects of different temperature, steam-to-DME mole rate and air speed on CuMn2O4/Al2O2 Bi-functional Catalyst were studied. The results showed that CuMn2O4 catalyst had higher DME conversion and H2 production rate than other two Catalysts. When steam-to-DME mole rate increased, DME conversion and H2 production rate of CuMn204 catalyst first rise and then be stabilized, the selectivity of CO2 increased and the selectivity of CO decreased. With a rise of air speed, DME conversion and H2 production rate would be first unchanged, and then decreased. The study is very important for fuel design of DME engine.
