Date are presented on the rate or oxidation of sulfur dioxide on a platinized silicia gel catalyst in a batch fluidized bed. The variables investigated were feed composition, space velocity, and temperature. The pressure was approximately one atmosphere. The data indicate that the rate of mass transfer was a substantial portion of the total resistance to reaction. The lack of suitable data for isolating the respective effects of mass transfer and chemical reaction prevented a correlation of the data. An apparent activational energy of 23,500 calories per gram-mol was established from reaction rate data alone. This compares with a value of 20,000 calories per gram-mol reported by other investigators.
