Abstract: The catalytic behavior of molybdenum doped lanthanum vanadate for propane oxidative dehydrogenation was investigated.It was found that the addition of molybdenum showed a positive promoting effect to propane oxidative dehydrogenation.56% and 43% of C3H6 selectivities were obtained over LaMo0.1V0.9O4.05 at 10% and 20% C3H8 conversion respectively ,while the selectivities on LaVO4 were only 36% and 22% at the isoconversion,which can be attributed to an increase of the mobile oxygen species beneficial to propene formation and to the change of the redox properties of the molybdenum doped catalysts.

Key words: Propane, Oxidative dehydrogenation, Rare earth catalyst
