英文摘要	sapo-11 molecular sieves were synthesized from nonaqueous media. the effects of si and al sources as well as solvents on the catalytic performance of sapo-11 were investigated by the hydroisomerization reaction of n-dodecane. the samples were characterized by xrd, xrf, n-2-adsorption, sem, nh3-tpd, ir-nh3 and si-29 cp mas nmr. the sapo-11 samples synthesized with tetraethoxysilane as the si source showed higher si incorporation contents than the sapo molecular sieves prepared with polymeric si sources (fumed silica and si colloidal gel). the reaction results showed that pt/sapo-11 catalysts synthesized from ethylene glycol and glycerol media with the monomeric si and al sources (tetraethoxysilane, aluminum isopropoxide) exhibited higher catalytic activities than those catalysts with the polymeric si or al (pseudo-boehmite) sources, due to the larger external surface area and higher acidity of the former ones. especially, the catalyst synthesized in an ethylene glycol medium possessed the highest catalytic activity. over this catalyst, 88% conversion of n-dodecane was achieved at a low temperature of 250 degrees c.
