稀土钙钛矿型燃煤催化剂的催化机理研究

稀土钙钛矿型催化剂是一类多功能催化剂,笔者简述了其结构性质,并对自制的催化剂进行XRD、SEM等实验,验证其主要成分为钙钛矿型氧化物、以及其表面孔隙发达满足用作催化剂的基本要求。最后结合热重分析实验,得出该催化剂对煤的燃烧有明显的促进作用,并且总结稀土钙钛矿型燃煤催化剂的催化燃烧的机理。 Rare earth perovskite catalyst is a kind of multifunctional catalyst;this paper introduces its character and structure simply,and made experiments of XRD and SEM.Thought the experiments to validate that the main com- ponent of the catalyst is perovskite,and fulfills the demands of catalyst.At last,combining with the thermogravim- etry to summarize the catalysis mechanism of combustion
