摘要:

分子筛因具有规则微孔结构、高比表面积及优异吸附选择性,在气体分离与净化领域应用广泛。然而,传统分子筛表面富含硅羟基(—Si—OH)与铝羟基(—Al—OH),在高湿度气体体系中易优先吸附水分子,这会导致孔道堵塞、目标气体吸附容量下降,进而严重限制分子筛对复杂工况的适用性。通过疏水改性调控分子筛表面化学性质与孔道环境,可显著提升分子筛抗水性能,成为解决该问题的核心技术。本文系统综述了分子筛疏水改性的方法(如硅烷偶联剂改性、表面包覆改性、脱铝改性与多方法协同改性),并阐述各方法的作用机理及改性效果;重点分析疏水改性分子筛在CO2捕获、挥发性有机化合物(VOCs)去除及其他污染物净化的应用进展;最后提出了疏水改性分子筛制备及其在气体净化应用中存在的问题,并对疏水改性分子筛的发展趋势进行了展望。

Abstract:

Zeolite is widely used in the field of gas separation and purification due to their regular microporous structure, high specific surface area and excellent adsorption selectivity. However, the surface of traditional zeolite is rich in silicon hydroxyl(—Si—OH ) and aluminum hydroxyl(—Al—OH ), and it is easy to adsorb water molecules preferentially in high humidity gas system, which will lead to pore blockage and decrease of adsorption capacity of target gas, thus seriously limiting the applicability of zeolite to complex working conditions. The surface chemical properties and pore environment of zeolite can be regulated by hydrophobic modification, which can significantly improve the water resistance of zeolite and become the core technology to solve this problem. In this paper, the hydrophobic modification methods of zeolite (such as silane coupling agent modification, surface coating modification, dealumination modification and multi-method synergistic modification) are systematically reviewed, and the mechanism and modification effect of each method are expounded. The application progress of hydrophobic modification zeolite in CO2 capture, volatile organic compounds (VOCs) removal and other pollutant purification is emphatically analyzed. Finally, the problems in the preparation of hydrophobic modification zeolite and its application in gas purification are put forward, and the development trend of hydrophobic modification zeolite is prospected.
