摘要

Response surface methodology(RSM) was applied to optimize the preparation process of La-Ce-Palygorskite catalysts for NO decomposition. The method of three-factors-three-levels central composition experiments were designed. The pH value of the chemical blending, ratio of La/Ce and calcination treatment temperature of the catalysts were chosen as casual factors. With RSM, the effects of these 3 factors on the response value was investigated. It has been found that the most active La-Ce-Palygorskite catalyst for NO decomposition can be prepared when the rare earth content, La:Ce, pH value of the chemical blending and calcination treatment temperature were 2%, La_xCe_(1-x)(x=0.55), 6.5 and 409°C, respectively. The denitration rate of the catalyst could be up to 66.58% under reaction conditions.
