含Ti蒙脱石纳米复合材料制备

Preparation of the Ti-containing montmorillonite nanocomposite materials

作为基质的蒙脱石具备良好的离子交换性能和一定的层反应空间 ,其特性有利于柱化物的层间交换。无机金属大离子基团柱联剂交联的多孔含Ti蒙脱石纳米复合材料 ,在有效控制交联剂TiO2 溶胶的制备及柱体分布前提下 ,可获得 :热稳定性≥ 870℃ ,比表面积≥ 350m2 /L ,层间开孔≥ 3 .5nm ,处于领先地位的石油催化、裂化超稳剂。

The montmorillonite acting as host possesses some properties which are suitable for interlayered exchange of pillaring agents due to its excellent ion change capacity and reasonable interlayer reaction space. Under the condition of effectively controlling the preparation of the pillaring agent TiO 2sol gel and distribution of the pillars, the Ti containing montmorillonite nanocomposite porous materials using the non ferrous big ionic group as its cross linking agent are superior stablizer for petroleum catalysis and cracking, which possess these sound qualities: thermal stability ≥870℃, specific surface area≥350m 2/L,interlayer free space≥3.5nm.
