Abstract:
A kinetic study has been performed for CO oxidation in hydrogen excess, i.e. under COPROX conditions, over CuO/CeO2 catalysts. Experiences under differential and integral reactor conditions have been made and a simple power-law type mathematical expression was obtained. The fitted parameters were activation energy (55 kJ mol-1) and partial orders of reaction (very close to 0 for O2 and 0.72 for CO). These results are consistent with mechanisms proposed in the literature for CO oxidation reaction. © 2008 International Association for Hydrogen Energy.
