英文摘要	Medium-pore molecular sieve sapo-11 was synthesized using an improved hydrothermal method, which involves programmed heating of the synthesis gel in the presence of isopropanol. products were characterized using x-ray diffraction, scanning electron microscopy, n-2 adsorption, ammonia temperature-programmed desorption, infrared spectroscopy of adsorbed pyridine, and si-29 solid-state mas nmr. the results indicated that the sapo-11 sample synthesized by this method showed higher crystallinity, smaller particle size, and larger micropore volume than that prepared by the conventional hydrothermal method. furthermore, the numbers of total acid sites and medium strength acid sites were also enhanced. in the hydroisomerization of n-tetradecane, the pt/sapo-11 catalyst thus exhibited high activity and selectivity for isomers.
