| 摘 要： | 以多级孔ZSM-5分子筛为载体，通过等体积浸渍法制备了一种双功能铁基催化剂，用于合成气直接制备芳烃。采用硅烷法合成不同硅铝比和介孔孔隙率的多级孔ZSM-5分子筛载体。催化剂的理化性质通过XRD、XRF、BET和HN3-TPD进行表征。结果表明：具有较高酸性的分子筛有利于提高油相中芳烃的选择性，当载体的硅铝比为40时，在油相中芳烃选择性可达66.9%；通过调节硅烷剂3-氨丙基三甲氧基硅烷（3-APTMS）的加入量来控制分子筛的介孔孔隙率，可使碳氢产物中芳烃的收率大幅度提高。 |

| Abstract: | A hierarchical ZSM-5 supported iron-based bifunctional catalyst was prepared by incipient wetness impregnation method, and applied to the aromatics production from syngas directly via Fischer-Tropsch. The hierarchical ZSM-5 zeolite of different silica alumina ratio and mesoporosity was prepared by adding silane. The physical-chemical properties of the catalysts were characterized by XRD, XRF, BET and HN3-TPD. Results indicated that zeolite with relative high acid amount was beneficial to the selection of aromatics in oil phase. When the silica-alumina ratio of zeolite was 40, the selectivity of aromatics in the oil reached 66.9%. In addition, the mesoporous volume of the zeolite can be adjusted by controlling the adding amount of 3-aminopropyltrimethoxysilane (3-APTMS), which may greatly increase the aromatics yield in the hydrocarbon. |
