中文摘要：

文章利用具有微、介孔双孔结构的机械混合分子筛催化剂（Ni/HZSM-5/SBA-15）,在较温和的反应条件下,将山梨醇一步水相芳构化转化为航空燃料范围内的芳烃和环烷烃类碳氢化合物。采用X射线衍射（XRD）、透射电子显微镜（TEM）、N_2吸脱附实验、NH_3程序升温解吸（NH3-TPD）等技术对催化剂的结构、形貌和酸性质进行了表征分析。催化剂反应性能测试结果表明：反应温度为320℃时,油相产率达到42.0%,芳烃含量为69.7%;当反应温度升高到360℃时,油相产率增加到61.3%。油相产物主要由环烷烃、支链烷烃和芳烃组成,通过后续加氢脱氧提质,可以转化为高品质的生物航空燃油添加剂。

英文摘要：

In this paper, under mild reaction conditions, renewable liquid fuels with high contents of aromatics and cyclic-hydrocarbons were synthesized over mechanically mixed zeolite catalysts （Ni/HZSM-5/SBA-15） with bimodal pore strictures by aqueous phase aromatization of biomass-derived sorbitol. Characterization techniques of N2 adsorption-desorption, X-ray diffraction （XRD）, transmission electron microscopy （TEM） and NH3 temperature-programmed desorption （NH3-TPD） were used to study the textural properties, phase compositions, acid behavior and morphologies of the catalysts. The test results showed that the liquid fuel yield of 42.0%with aromatics content of 69.7%was achieved at 320℃, and the oil yield further increased to 61.3%at reaction temperatures up to 360℃. The synthetic hydrocarbons, mainly consisting of cycloalkanes, branched-alkanes and aromatics, would be used as additives of renewable aviation fuels after simply upgrading by hydrodeoxygenation （HDO）.
