摘要/Abstract

摘要： 采用导向剂法，以聚乙二醇-600（PEG-600）为形貌控制剂和分散剂，制备了具有薄片状形貌的小晶粒Y型分子筛。通过X射线衍射（XRD）、扫描电镜（SEM）、N₂吸附-脱附、吸附吡啶的原位红外和NH₃程序升温脱附（NH₃-TPD）技术对合成的Y型分子筛及制备的催化剂进行了表征。结果表明，所合成的Y型分子筛大部分呈薄片状形貌，相对于传统八面体形貌Y型分子筛来说，具有较高的外比表面积。1，3，5-三异丙基苯的催化裂化反应结果表明，与传统八面体形貌的Y型分子筛制备的催化剂相比，薄片状Y型分子筛具有较高的1，3，5-三异丙基苯裂化活性和裂化产物选择性。

Abstract: The Y zeolite with sheet-like morphology was synthesized by directing agent method, using polyethyleneglycol-600 as the morphology control agent and dispersion agent. Characterization of the molecular sieves and the catalysts was performed using SEM, XRD, N₂ adsorption-desorption, Py-FTIR and NH₃-TPD. Results showed that the prepared sheet-like molecular sieve had high external specific surface area. The catalytic cracking properties of the catalysts prepared with industrial octahedral and sheet-like NaY zeolites were investigated by using 1,3,5-triisopropylbenzene as the probe molecule. The experimental results showed that the catalyst with sheet-like morphology displayed higher conversion of 1,3,5-triisopropylbenzene and cracking products selectivity, compared to the industrial octahedral zeolite.

Key words: Y zeolite, polyethyleneglycol-600, sheet-like morphology, 1,3,5-triisopropylbenzene, catalytic cracking
