The small-grain mesoporous SAPO-11 molecular sieve was successfully prepared by the directing agent method under the condition that the amount of the template was halved. The crystal structure, elemental composition, surface area, pore volume, and acidity of the catalyst were thoroughly characterized. The catalytic hydroisomerization performance of SAPO-11 catalysts with 0.5(wt)% Pt loading was evaluated with n-dodecane as a material. The results showed that the size of SAPO-11 molecular sieve with reduced templating agent content is about 3μm, the mesoporous specific surface area is 113.3m²/g, the mesoporous pore volume is 0.328m³/g, and the isomer yield is 65.31%.
