 Abstract: For the first time, we reported on a highly selective propane dehydrogenation to propene over SiO2- supported dispersed VOx species under oxygen-free and oxygen-lean conditions. Propene selectivity above 80% was achieved with propane conversions above 45% at 823–843 K. At operation under oxygenlean conditions, consecutive propene conversion to COx was significantly suppressed and propene was formed additionally via the highly selective non-oxidative dehydrogenation route over the same catalyst. Usage of SiO2 supports (MCM-41, SBA-15, SiO2) with no strong acid sites and co-feeding of small O2 amounts lead to very limited coke formation (<2 wt. % after 20 h on-stream operation). This results in only slight decrease in time-on-stream performance (ca. 10% of deactivation during 20 h).
