Abstract
Temperatures within and near to single pellets of tin/antimony oxide used to catalyse the oxidative dehydrogenation of butene to butadiene have been measured and the results compared with values predicted by a mathematical model. The observed temperature difference was up to 10°C, depending on the reaction conditions, with the major change in temperature occurring across the gas film near to the surface. The mathematical model describes these observations with reasonable accuracy, and discrepancies are discussed in terms of the parameters that are used in the calculation. The derived temperature difference is found to be particularly sensitive to values of bulk concentrations and film heat transfer coefficient, and to be less responsive to values of bulk density and effective diffusivity.
