Y型沸石经水热超稳化处理后,其结构、吸附性能和酸性等均发生改变,从而改善了沸石催化剂的催化活性、选择性和稳定性.Y型沸石在水热脱铝过程中形成的非骨架铝(EFAL)的研究,愈来愈受到重视.但EFAL及其经化学方法的脱除对沸石物化性能和催化性能的影响,以及EFAL的状态和对酸性的贡献等一系列问题,文献上尚 Y-type zeolite after hydrothermal super-treatment, the structure, adsorption properties and acid were changed, thereby improving the catalytic activity of the zeolite catalyst, selectivity and stability of the Y-type zeolite in the hydrothermal dealumination process Of the non-framework aluminum (EFAL) research, more and more attention.But EFAL and its removal by chemical methods on the physical and chemical properties of zeolites and catalytic performance, as well as the state of EFAL and the contribution to the acid and a series of problems, The literature is still
