用常规方法制备了一系列Ｙ型分子筛，测定了其热稳定性、催化裂化及氢转移活性。采用模式识别方法，对Ｙ型分子筛组成与其催化裂化性能的关系进行了深入的分析，其结果有助于催化裂化催化剂的设计和信息积累。
A series of Y zeolites were prepared by conventional methods and their thermal stability, catalytic cracking and hydrogen transfer activity were measured. The pattern recognition method was used to analyze the relationship between the Y-type molecular sieve composition and its catalytic cracking performance. The results are helpful for the design and information accumulation of catalytic cracking catalysts.
