This work is dedicated to construction of kinetic model for the process of H2S selective oxidation into elemental sulfur at carbon nanofibrous (CNF) catalyst. The experiments included the CNF synthesis and kinetic studies. The modified minimization procedure was proposed for kinetic modelling, model discrimination and determination of kinetic parameters. The selected kinetic model provides the qualitatively adequate and quantitatively accurate description of experimental results in a wide range of temperatures (155–250 °C), H2S (0.5–2 V%) and O2 (0.25–10 V%) concentrations and reaction mixture humidity (0–35 V% of water vapor). The average value of deviation in the experimental and calculated concentration of key reactants (H2S, O2, SO2) does not exceed 0.04 V%. Such value is comparable with the mean error in maintenance and control of these concentrations in experiments, so the overall model accuracy may be estimated as quite high. The constructed model may be applied for the mathematical modelling, engineering and scale-up of different H2S oxidation processes, based on the CNF catalyst.
