Hydrogen production by catalytic partial oxidation and reforming of DME was successfully carried out at an ambient pressure and 600750 degrees C. An H-2 yield of more than 90% was obtained with little methane production over Pt/Al2O3 and Ni-MgO combined catalysts. Ni-MgO was active for the reforming of DME as well as for the reforming Of CH4, which formed through a homogeneous reaction between DME and oxygen. The hybrid catalyst gave a better performance than the dual-bed ones. High temperature and high W/F were favorable to H-2 yield by improving the reforming reaction. (c) 2005 Elsevier B.V.
