Abstract

The effect of iron substitution on bulk and TiO2-supported VOPO4⋅2H2O on the catalytic performances in oxidative dehydrogenation of ethane has been studied in a fixed-bed reactor at 550 °C. The samples have been characterized by XRD, BET measurements, TPR and ammonia TPD experiments. A uniform dispersion of the active phase on the support has been obtained. Both iron substitution and dispersion on TiO2 significantly modify redox and acid properties of vanadyl orthophosphate. A good correlation between the acid and redox properties of the catalysts and their catalytic performances has been observed.
