Studies on Propane Oxidative Dehydrogenation over Pure Rare Earth-Based Catalysts

Abstract

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%.

Key words: Propane, Oxidative dehydrogenation, Rare earth catalyst, Propene
