Influence of preparation methods (i.e. co-precipitation, chelating, citric acid and critical phase) on the preferential oxidation of CO in excess hydrogen over CuO-CeO 2 catalysts has been investigated. CuO-CeO 2 catalysts are characterized by using BET, X-ray powder diffraction (XRD), UV Raman and
The kinetics of CO and H 2 oxidation over a CuO-CeO 2 catalyst were simultaneously investigated under reaction conditions of preferential CO oxidation (PROX) in hydrogen-rich mixtures with CO 2 and H 2 O. An integral packed-bed tubular reactor was used to produce kinetic data for power-law kinetics
