Sr-V-Mo oxides supported on γ-Al2O3 are promising catalysts for oxidehydrogenation of propane to propylene. Sr doped V-Mo catalysts showed a much better performance compared to the parent catalyst. The effects of reaction temperature and space time on the performance of the Sr doped catalyst are discussed. Upon increasing reaction temperature (450-550 ℃), the conversion increased without affecting the selectivity. Increasing the space time increased both the conversion and selectivity. These results confirmed the previous findings of the role of Sr in stabilizing the catalyst by lowering its reducibility. Characterization results using BET, SEM and FTIR provided further confirmation of these findings.
