Abstract: The hydroisomerization of n-paraffins is a crucial process for producing high-octane gasoline and low-freezing-point aviation kerosene, with the yield and selectivity of isomerization products primarily constrained by the development of bifunctional catalysts. This study started from the reaction pathways and mechanisms of hydroisomerization, and primarily summarized the research progress in the modification and control of the structural properties and acidity of SAPO-11 molecular sieves. The effects of the crystal size, pore structure, and acidity of SAPO-11 molecular sieves on the catalytic performance of SAPO-11-based hydroisomerization catalysts were discussed in detail. Furthermore, the future development directions of hydroisomerization catalysts and SAPO-11 molecular sieves were summarized, and prospects were proposed.

Key words: n-alkane, hydroisomerization, SAPO-11 molecular sieve, small-sized crystal, hierarchical pore, acid property
