Abstract
The heterogeneous reaction between solid sodium carbonate and gaseous sulphur dioxide of partial pressures from 1.2 to 7.5 kPa has been investigated in a fixed-bed reactor at temperatures of 54 and 81 °C in the presence of water vapour of partial pressures from 0.30 to 1.25 kPa. An independence of the reaction course of the sulphur dioxide content in the gas phase and a linear dependence of the reaction rate on the partial pressure of water vapour were found under the above conditions. The rate equation derived previously has been simplified and the set of differential equations describing the reaction in a fixed bed has been solved. The relations obtained have been applied to an evaluation of the effective rate constant. The true rate constant has been estimated to be independent of temperature.
