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.
