THE KINETICS OF SO2 OXIDATION FOR VARIOUS CATALYST COMPOSITIONS

The sulfur dioxide to sulfur trioxide conversion has been measured for three different automotive exhaust catalysts. Two of the catalysts were 1975 production catalysts (Engelhard IIB and Matthey-Bishop 3C) and the third is a palladium catalyst on a monolith support. The measurements were made using a flow reactor with simulated exhaust gas and show that, while the carbon monoxide and propylene conversions were very similar for all three catalysts, there was a wide range of sulfur dioxide conversions. /GMRL/
