    • Abstract

       

      Alkali-ion promoted iron oxide was used as a catalyst for the non-oxidative dehydrogenation of ethylbenzene to styrene. Catalytic performance studies showed high activity, with selectivity ≈93% and conversion ≈49%. The fresh and used catalysts were characterised by various physicochemical techniques like scanning electron microscopy, x-ray diffraction and Mössbauer spectroscopy. X-ray and Mössbauer data clearly show the presence of α-Fe2O3 and Fe3O4 in the used catalysts and α-Fe2O3 in the fresh catalyst, the phases being identified from their standardd values and hyperfine interaction parameters.
