Influence of redox properties on the activity of iron oxide catalysts in dehydrogenation of propane with CO2
Different Fe-containing catalysts (pure Fe2O3, Fe2O3 supported on active carbon or gamma-Al2O3, and hydrotalcite-derived Mg-Fe oxides) were examined in the dehydrogenation of propane performed in an Ar or CO2 atmosphere at 873 K. A promoting effect of carbon dioxide was found for the Fe2O3 and Fe2O3/AC samples. The catalytic results are discussed in terms of redox properties of the catalysts, determined by temperature-programmed reduction (TPR).
