| Abstract: | Different Fe-containing catalysts (pure Fe2O3, Fe2O3 supported on active carbon or g-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).
