Wash-coated alumina catalysts introduced into micro-channels were applied for the water-gas shift reaction. The application standing behind this work was catalytic CO clean-up of reformate with the aim of hydrogen generation for mobile fuel cell systems. Bimetallic Pt/CeO 2 /Al 2 O 3 , Pt/Rh/CeO 2 /Al 2 O 3 , Pt/Pd/CeO 2 /Al 2 O 3 and Pt/Ru/Al 2 O 3 catalysts were tested in a standard screening protocol under the conditions of high-temperature shift (9.1% CO, 290, 315 and 340°C reaction temperature) and low-temperature shift (2.6% CO, 290, 315 and 340°C reaction temperature) at a WHSV of 100Ndm 3 /(hg cat ). Methane, was formed as the only by-product. Pt/CeO 2 /Al 2 O 3 was identified as the best candidate concerning selectivity and activity. The optimum platinum content was found to range between 3 and 5wt.%, whereas the optimum ceria content ranged between 12 and 24wt.%. The calcination temperature and platinum metal salt solution applied during catalyst preparation had a drastic effect on the activity of the Pt/CeO 2 /Al 2 O 3 catalyst.
