摘　　要：以价格低廉的铈和锰为活性组分,采用水热合成法合成催化剂CePO_(4)和催化剂15%Mn/CePO_(4),考察合成方法、焙烧温度、水热合成温度、O_(2)浓度、NO含量及V(NH_(3))∶V(NO)对催化剂15%Mn/CePO_(4)低温脱硝活性的影响,得出催化剂15%Mn/CePO_(4)低温脱硝最佳工艺条件:合成方法为水热合成法,焙烧温度500℃,水热合成温度150℃,O_(2)浓度3.5%,NO含量780×10^(-6),V(NH_(3))∶V(NO)=0.8。CePO_(4) and 15%Mn/CePO_(4) catalysts were synthesized by hydrothermal method using low cost cerium and manganese as the active components.The effects of synthesis method,calcination temperature,hydrothermal temperature,O_(2) concentration,NO concentration and NH_(3)/NO ratio on the low temperature denitrification activity of 15%Mn/CePO_(4) were investigated.The optimum process condition for 15%Mn/CePO_(4) low temperature denitrification catalyst were obtained as follows:hydrothermal method,calcination temperature 500℃,hydrothermal temperature 150℃,O_(2) concentration 3.5%;NO concentration 780 ppm;NH_(3)/NO ratio 0.8.
