Abstract Abstract： The performance of catalysts prepared by mechanically mixing dimethyl ether (DME) hydrolysis active components and methanol reforming active components were compared in the DME steam reforming reaction. The effects of different active components and different calcination temperatures of CuMnspinel were studied. The results show that HZSM5 (nSiO2/nAl2O3=38) has the highest H2 production rate among different DME hydrolysis active components. CuMnspinel has high H2 production among different methanol reforming active components. CuMnspinel that was calcined by 700 °C exhibits the highest activity for DME steam reforming. The result shows that DME conversion is 99.65% and H2 production is 73.15% at 350 °C when used the bifunctional catalyst composed of CuMnspinel(700 °C) and HZSM5(38). The study is very important for fuel design of DME engine.
