Abstract

The influence of the ratio of active components (Fe and Cr) on the catalytic activity of FeCr/C catalysts in the oxidative dehydrogenation of ethane with CO2 was analyzed. The best results were achieved on the 2Fe3.7Cr/C catalyst, in which the Fe : Cr ratio corresponded to the stoichiometry of iron(II) chromite FeCr2O4. The physicochemical characteristics of the prepared catalysts were determined and analyzed (XRD, XPS, magnetometry). Based on the totality of the data obtained, it is possible to assume the presence of the iron(II) chromite phase.
