Abstract: The pure rare earth-based complex catalysts such as CeO2/2CeF3, La2O3/4CeF3, Sm2O3/ 4CeF3 were prepared.These catalysts were very active in oxidative dehydrogenation of propane, and the selectivity to propene was very high.At 500℃ and 6000 h-1, using CeO2/2CeF3 as the catalyst with Ce2Oas the promoter, the conversion of propane was 41.3%, selectivity to propene reached 81.1%, propene yield was 33.5%.After 84 hours, the catalyst remained activive, the yield of propene still attained 31.7%.
