Abstract: A thermodynamic model for a quasi-homogeneous oxidation of sulfur dioxide in a stationary catalyst bed was developed. It was demonstrated that there is a one-parameter set of autowave (limited) solutions to the mathematical model for the propagation of thermal waves. An analysis of the distribution of the local production of entropy over the space-time coordinate was performed. The total production of entropy in a distributed open system was shown to be a function of the autowave solution. A single solution satisfying the principle of minimum production of entropy (lowest energy dissipation) was selected from the continuum of autowave solutions. A variational formulation of the procedure for calculating the characteristics of thermal waves was suggested, which is more advantageous from the practical point of view than the procedure of truncation (setting at zero) of the chemical reaction rate.
