The oxidative dehydrogenation (ODH) of n-octane to produce octene at atmospheric pressure has been studied using an industrially supplied iron molybdate catalyst from Johnson Matthey (JM). In situ X-ray diffraction studies revealed at temperatures ≥450 °C the catalyst undergoes a reductive phase transition when reacted with noctane at 450 °C where the phase changes from Fe2(MoO4)3-MoO3 to FeMoO4-MoO2-Mo4O11. As a result, if the temperature is taken back below this point the catalyst does not revert to the original phase and therefore the same activity and selectivity cannot be achieved.
