Kinetics of ODH of ethane to ethylene with lattice oxygen of VOx/Al2O3–ZrO2. Catalyst lattice oxygen favors high ethylene selectivity up to 82%. The depletion of catalyst lattice oxygen is modeled using TPR data. Series-parallel reaction network is developed using CREC Riser Simulator data. A Langmuir–Hinshelwood model satisfactorily predicts the experimental data.
