稀土钙钛矿型燃煤催化剂的催化机理研究

The Research of Rare Earth Perovskite Coal Combustion Catalyst of Mechanism of Catalysis

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 muhifunctional catalyst ; this paper introduces its character and structure simply, and made experiments of XRD and SEM. Thought the experiments to validate that the main component of the catalyst is perovskite, and fulfills the demands of catalyst. At last, combining with the thermogravimetry to summarize the catalysis mechanism of combustion.
