摘　　要：由于小粒径、多级孔或兼具小粒径与多级孔结构的SAPO-11分子筛能够显著提高SAPO-11分子筛催化剂在烃类加氢异构化中的活性和选择性,近年来已成为烃类异构化催化剂研究的热点。本文按照SAPO-11分子筛的制备方法进行分类,系统介绍了小粒径、多级孔和兼具小粒径与多级孔结构的SAPO-11分子筛的制备及其临氢异构化性能,指出在今后的研究中,研究开发新的绿色高效合成方法,降低合成成本和减少环境污染是小粒径或(和)多级孔SAPO-11分子筛催化剂实现工业化应用亟待解决的突出问题和研究方向。SAPO-11 catalyst with reduced particle size,hierarchical pores or both can significantly improve the activity and selectivity in the hydroisomerization of hydrocarbons,which has become a hot research topic in recent years.In this paper,the synthesis methods,structural characteristics and hydroisomerization performance of SAPO-11 molecular sieves of small particle size,hierarchical structure and with both small particle size and multi-stage pore structure are systematically introduced.It is pointed out that the research and development of new green and efficient synthesis methods,reducing the synthesis cost and environmental pollution should be the future research directions for the industrial application of small particle size or/and hierarchical SAPO-11 molecular sieve.
