Comparative study of catalytic behaviour of bulk-like and highly dispersed supported vanadyl orthophosphate catalysts in the oxidative dehydrogenation of ethane
The catalytic behaviour in the oxidative dehydrogenation of ethane of TiO2- and SiO2-supported catalysts containing bulk-like VOPO4 particles has been compared to that of TiO2-supported highly dispersed VOPO4. The catalysts have been characterised by XRD analysis and BET measurements. Redox properties have been studied by TPR experiments. A correlation of catalytic activity and C2H4 selectivity with redox properties has been proposed.
