摘　　要：为使燃烧催化剂满足燃烧体和环保的要求,研制了以粉煤灰为载体、以稀土和二氧化锰为活性组分的钙钛矿型燃煤催化剂。催化剂的制备采用浸渍法,经过120℃干燥、850℃焙烧活化。X射线衍射图表明该催化剂主要成分是LaMnO3。热重分析表明,添加钙钛矿型催化剂可以促进煤炭的燃烧,提高燃烧速率,使煤的着火点温度降低10℃、失重速率最大温度降低19℃、燃烧结束温度提前21℃。This paper introduces the preparing process and catalysis of the perovskite catalyst. Catalyst was prepared by impregnation method, through drying under 120 ℃, burning in 850 ℃, finally to get the rare earth and manganese dioxides coal combustion catalyst with the structure of perovskite, for example LaMnO3. Using the thermogravimetry （TG） to reach its effect on coal burning, and the experiment indicates that through burning, adding this catalyst advanced coal combustion could accelerate velocity of burning, the ignition temperature, the temperature of losing the weight biggest, and the temperature of end are all ahead from 10℃ to 21 ℃.
