Kinetics of preferential CO oxidation in H2 excess (COPROX) over CuO/CeO2 catalysts

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 ac...
