磷改性分子筛的研究进展

Research development in phosphorus modification of molecular sieves

综述了国内外采用磷化合物改性沸石分子筛(ZSM-5、Y、β和MCM-41等)的研究进展,重点介绍了改性后沸石分子筛的结构、催化活性,水热稳定性和表面酸性以及其催化反应等方面的变化,同时对磷改性沸石分子筛的应用前景进行了展望。

The advance in phosphorus modification of the molecular sieves, such as ZSM-5, Y, 13 and MCM-41, etc. , was reviewed. The structure, catalytic activity, hydrothermol stability and surface acidity of the zeolite molecular sieves after modification were introduced emphatically, and the reaction mechanisms were also evaluated. The application prospects of phosphorus modification of the molecular sieves were outlined.
