Abstract
The oxidative dehydrogenation of ethane into ethylene using CO2 as an oxidant at temperatures of 650-750 °C was carried out over Fe/C, Cr/C and Fe-Cr/C catalysts deposited on a carbon support. Before and after the reaction the catalysts were investigated by X-ray powder diffraction (XRD), in situ magnetometry and transmission electron microscopy methods. The correlation between activity of Fe/C, Cr/C and Fe-Cr/C catalytic systems and their phase composition was established.
