制备方法对Fe-Mn/ZSM-5/CC催化还原NOx性能的影响
Study of the Effect of Preparation Method on the Catalytic Reduction of NOx over Fe-Mn/ZSM-5/CC
摘要
Abstract
Solution impregnation ,slurry dip coating and ultrasonic assisted dip coating were a‐dopted to prepare three kinds of Fe‐Mn/ZSM‐5/CC (CC :cordierite) monolithic catalysts .Their performance in catalytic reduction of NO x was studied .N2 adsorption and desorption ,XRD and SEM were used to explore the structure and properties of the catalysts .The results show that the catalyst preparation methods had significant impact on the performance of Fe‐M n/ZSM‐5/CC monolithic catalysts in catalytic reduction of NO x .The catalyst produced by ultrasonic assisted dip coating showed the best catalytic performance when compared with those prepared by solution impregnation or slurry dip coating .The reason was explained by its larger specific surface area , more uniform coatings and mesoporous structure .Its conversion rate was above 90% in the tem‐perature range of 180~430 ℃ .关键词
