The activity of a 5-wt% Cu/CeO2x catalyst during preferential CO oxidation in hydrogen-rich gas mixtures was studied in a microchannel reactor. The CO concentration dropped from 1 vol.% to 10 ppm at a selectivity of 60%, at a temperature of 190 8C, and a weight hour space velocity (WHSV) of 55,000 cm3 g1 h1. Both the CO concentration and the temperature increased when the WHSV was increased from 50,000 to 500,000 cm3 g1 h1. An increase of the O2 concentration from a 1.2 to 3 fold excess reduced the CO concentration to 10 ppm in a broad temperature interval of 50 8C at WHSVs up to 275,000 cm3 g1 h1. The preferential CO oxidation could be carried out at higher flow rates and at higher selectivities in the microchannel reactor compared to a fixed-bed flow reactor.
