ZSM-5 molecular sieve has an important application value in industrial adsorption. Due to the existence of micropores, it is hard for larger molecules to enter the ZSM-5 molecular sieve. Meso-microporous MFI zeolite was prepared by hydrothermal crystallization regarding the organosilane as the structure-directing agent. Then the samples were characterized by X-ray diffraction, infrared spectroscopy and so on. The effect of organosilane on mesoporous volume and the mechanism of mesoporous formation were further investigated. Finally the performance of adsorption for volatile organic compounds (VOCs) on meso-microporous ZSM-5 were analyzed by static adsorption and dynamic adsorption experiments.

介孔体积可控的介孔微孔ZSM-5的合成及形成机理分析

ZSM-5分子筛在工业吸附方面具有重要的应用价值。由于微孔的存在，较大的分子很难进入ZSM-5分子筛。以有机硅烷为结构导向剂，通过水热结晶制备了介孔微孔MFI沸石。然后对样品进行X射线衍射、红外光谱等表征。进一步研究了有机硅烷对介孔体积的影响以及介孔形成的机理。最后通过静态吸附和动态吸附实验分析了中微孔ZSM-5对挥发性有机化合物(VOCs)的吸附性能。
