The research advance in synthesis of Y zeolite from kaolin were reviewed. The synthesis of Y zeolite with different methods such as in-situ synthesis of Y zeolite by kaolin microsphere,the synthesis of nanosized molecular sieves,the synthesis of high silica Y zeolite,and other methods were introduced. The analysis and comparison of various raw materials and different synthetic methods were given. Y zeolite synthesized by in-situ crystallization technique from kaolin clay was the most important method for obtaining excellent FCC catalysts. Recent progress in in-situ crystallizing technique was also reviewed. The research on synthesis of special Y zeolite with excellent performance ,especially the synthesis of nanosized and high silica Y zeolite,was focused on. The methods for preparing nanosized Y zeolites,such as optimizing synthesis conditions,adding dispersant agents and microwave synthesis,were described. Y zeolites with high molar ratio of silica to alumina was synthesized by direct synthetic method and secondary synthetic method;the direct synthetic method had the disadvantages of harsh reaction conditions and raw material waste;the secondary synthetic method possessed long process flow,which resulted in the enhancement of synthesis cost. The new synthesis methods of Y zeolite,such as ionothermal synthesis,dry gel conversion method and synthesis of composites Y zeolite from kaolin were also summarized in this paper. The research directions and prospects of Y zeolites synthesis were outlined.
