摘要：

In hydrothermal system, high silica zeolite Y with the maximum framework Si/Al (molar ratio) of 3.1 was prepared by using aluminosilicate gel as source. Organic amine was not used in this system. The thermal stability of synthesized sample was better than that of commercial zeolite HY. The crystal diameter of the synthesized sample was smaller than that of commercial zeolite NaY, indicating that it may be used as nanosized catalyst.
