英文摘要： This project set the study on in-situ microprocess of crystallization as a breakthrough point, aiming at the key problems of low yield and serious pollution in the synthesis of nanosized zeolite Y, to develop the green and high yield hydrothermal synthesis method for nanosized zeolite Y as well as the crystallization mechanism of the zeolite via the works on selecting the raw materials and adjusting its ratios, tuning the synthesis conditions, and tracking the aggregation reaction of silica,aluminium,templete,and so on. In the project, the synthesis method and technological process with properties of good maneuverability and repeatability will be designed for the purpose of green and high yield synthesis. To deeply investigate the formation mechanism of the zeolite, the effect of raw material and synthesis system on the product is studied. Via the control on the composition and state of the synthesis solution and exploration of the intrinsic factors that affect the state and aggregation manner of each species, the general methods of control of the sort and properites of the product are established. For the expoitation of new type zeolite and deeply understanding the mechanism of the zeolite formation, studies on the aggregation process and its state control method on silica, aluminium, template, et al have very
