The rate of sulfur dioxide oxidation over activated carbon was measured in gaseous stream of sulfur dioxide-oxygen-nitrogen mixtures. It was found that catalyst fouling during the reaction was caused by sulfur trioxide formed on carbon. According to the Langmuir-Hinshelwood model, the over-all rate equation was derived on the basis of the mechanism where the rate-determining step is a surface reaction. The rate data were well correlated with the rate equation.
