Abstract
CO impedes the low temperature (<170°C) oxidation of C 3H 6 on supported Pt. Supported Au catalysts are very effective in the removal of CO by oxidation, although it has little propene oxidation activity under these conditions. Addition of Au/TiO 2 to Pt/Al 2O 3 either as a physical mixture or as a pre-catalyst removes the CO and lowers the light-off temperature (T 50) for C 3H 6 oxidation compared with Pt catalyst alone by ∼54°C in a feed of 1% CO, 400 ppm C 3H 6, 14% O 2, 2% H 2O.
