The investigation included the elaboration of the transient kinetic model of oxidative dehydrogenation of butene-1 to butadiene at Sb–Sn oxide catalyst on the basis of the experimental data and the mathematical modeling of this processes in non-stationary regimes under periodical cycling of initial reagents concentrations. The influence of residence time, amplitude and duration of periodic cycles, ratio of reagents concentrations within the cycle on the process parameters was numerically studied. It has been shown that process performance in unsteady state under forced oscillation of reagents concentration significantly increases the overall yield of butadiene in comparison with the steady-state one. The benefits of the nonstationary process may be realized under technologically acceptable values of process parameters.
