表面活性剂改性的铝交联蒙脱土的表征及催化性能

Characterization and Catalytic Activities of Alumina Cross Linked Montmorillonites by Surfactant Modification

以聚乙烯乙醇为支撑前体，合成了一类新型的表面活剂改性的铝交联蒙脱土（ＡｌＳＣＬＭ）。通过ＸＲＤ，低温Ｎ２脱吸附分析，骨架振动红外光谱等手段的表征及对催化转化柴油为汽油的测试。

A new kind of alumina cross linked montmorillonites by surfactant modification was prepared in the presence of polyvinyl alcohol as a pillaring precursor. Through the characterization of XRD,low temperature N 2 adsorption desorption measurements, IR framework vibration spectra and the test of microactivity, it is found that Al SCLM has higher thermal stability and higher catalytic activity for converting diesel into gasoline than conventional Al CLM.
