Abstract

Hydrogen production from the dry reforming of methane has been studied over MAl2O4 (M = Cu2+, Ni2+ or both) with respect to the structure, surface properties and coke deposition of the spinel oxides. The catalysts were characterized by Raman, XPS, TEM, and N-2 adsorption isotherms methods. The Ni/NiAl2O4 system was significantly more active due to the intimated contact between Ni-o specie and the NiAl2O4. This system is found to give carbon filaments which easily react with CO2, in comparison with the Cubased spinel oxides. (C) 2009 Elsevier B.V. All rights reserved.
