An unsteady-state mathematical model for condensed sulfur formation by catalytic hydrogen sulfide oxidation in a fixed catalyst bed is proposed. Analytical solutions for the model are obtained. The steady-state front of hydrogen sulfide oxidation is shown to occur. The front velocity, the time of front formation, and the effect of the catalyst activity on front formation are estimated. The analytical solutions are compared with experimental data.
