| Abstract: | 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. |
| Keywords: | catalyst hydroisomerization SAPO-11 molecular sieve small particle size hierarchical |
