The influence of the catalyst loading, the active components, and the size of the pellets on the conversion were discussed. Over a CeCuM′M″ catalyst at 25000h-1 the CO could be oxidized about 53.4% at 150°C. The radial distribution of the rare earth Ce, and the transitional metals M′ and M″ were homogeneous, but Cu increased gradually from the centre to outside of the pellets.
