| Abstract: | A MoVTeNbO catalyst was prepared by sol gel method and effects of reaction temperature, GHSV, feed proportion and water content in the feed on behaviors of the catalyst for selective oxidation of propane to acrylic acid were investigated. The results showed that the precursor prepared under reaction temperature 400 ℃, GHSV 1 800 h-1and n(C3H6)∶n(O2) ∶n(Ar) ∶n(H2O)=4.4∶12.8∶36.9∶15.3 exhibited good catalytic activity, with propane conversion of 60%, selectivity to acrylic acid of 49.9% and yield of acrylic acid of 30%. |
