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.
