Abstract:
The kinetics of H2S oxidation with atmospheric oxygen over V2O5 has been investigated at temperatures of 150–250°C, O2/H2S > 4 mol/mol, and initial H2S concentrations of up to 3 vol %. In spite of the large excess of oxygen over hydrogen sulfide, the H2S conversion rate depends on the oxygen concentration and does not depend on the hydrogen sulfide concentration. The temperature dependence of the H2S conversion rate differs markedly from the Arrhenius dependence and is nearly linear. The SO2 formation rate obeys the Arrhenius equation. The mechanism suggested for hydrogen sulfide oxidation includes SO2 and liquid sulfur formation steps and the interaction between H2S and SO2 in a liquid sulfur film. Reaction rates have been calculated for this reaction mechanism. The calculated rates coincide with experimental data. Numerical values of rate constants have been obtained for the liquid_phase interaction between H2S and SO2.
