Abstract:

SSZ-13 zeolite has been widely used in many fields because of its special pore structure and physicochemical properties. Some conventional synthesis methods of SSZ-13 zeolite in recent years are summarized, including hydrothermal synthesis, solid grinding, dry-gel conversion, interzeolite conversion and ultrasound, microwave or seed addition assisted synthesis, and the advantages and disadvantages of these methods are discussed. In addition, the effects of templates, the composition and ratio of raw materials, and the crystallization conditions on the synthesis of SSZ-13 zeolite are presented. Finally, the effects of metallic additives and pore structure on the catalytic performance of SSZ-13 zeolite are discussed, which suggests that the modification methods and the catalytic mechanism of SSZ-13 zeolite will be the hot topics in the future.

Key words: molecular sieve, synthesis, influencing factors, modification, catalyst

摘要:

SSZ-13分子筛由于其特殊的孔道结构和物化性质,被广泛应用于许多领域。本文综述了近年来SSZ-13分子筛的一些常规合成方法,包括水热法、固相研磨法、干胶转换法、转晶法以及超声、微波或加入晶种辅助合成,并对这些方法的优点和不足进行了评价;介绍了模板剂、原料组成及配比和晶化条件对SSZ-13分子筛合成的影响,指出寻找廉价的模板剂、明确这些因素的影响方式具有重要的研究意义;概述了金属改性和引入介孔改性对SSZ-13分子筛催化性能的影响,并提出寻找更为有效的改性方法、深化机理研究是SSZ-13分子筛今后研究的重点。
