| 摘 要： | 采用钛酸丁酯溶胶法制备了钛基柱撑黏土(Ti-PILC),通过浸渍法制备Mn-CeOx/Ti-PILC,运用BET、FT-IR、XRD、NH3-TPD、XPS等技术对催化剂进行表征分析。结果说明,经过钛交联柱撑制备的Mn-CeOx/Ti-PILC是一种具备较大比表面积(133.7 m2/g)的多孔性介孔材料;活性成分主要为CeO2以及Mn2O3。Mn-CeOx/Ti-PILC低温下具有较好的选择性能催化剂还原(SCR)脱硝活性,180 ℃下,脱硝活性达到83.1%。

| Abstract: | Titania-pillared clay(Ti-PILC) was prepared from butyltitanate,then Mn-CeOx/Ti-PILC was prepared by impregnating method on the Ti-PILC.The catalysts were characterized by BET,FT-IR,XRD,XPS and NH3-TPD.The results showed that,the pillaring process was efficient.Active components exist in Mn2O3 and CeO2 in catalyst Mn-CeOx/Ti-PILC which was a porous mesopore material with high BET surface area(133.7m2/g),the activity test also indicted that this catalyst had good de-NOx activity,the removal efficiency could reach 83.1% even at 180℃. |
