A series of well-defined and uniform pore-structure (WDUPS) supports with almost identical pore structure, but different surface chemical properties were obtained. Such an approach allows the efficient elimination of the pore structure effect that could not be achieved in the case of conventional supports. Fe was introduced into the as-prepared WDUPS supports by incipient wetness impregnation to obtain WDUPS Fe-based catalysts for investigating the support effects on Fischer–Tropsch synthesis. Based on the reaction results, the Fe₂O₃ supported on the WDUPS SiO₂ exhibited the highest CO conversion and C_2-4 olefins selectivities. The other three WDUPS catalysts, whose supports were WDUPS Al₂O₃, TiO₂, and ZrO₂, were a favor to form C₅₊ hydrocarbons during Fischer–Tropsch synthesis. The highest C₅₊ hydrocarbons selectivity could be obtained over the Fe-based WDUPS catalyst using WDUPS Al₂O₃ as support. It was proposed that the support effects on the catalytic behaviors obtained in this research work are more reliable than those obtained before by using conventional supports with vague tortuosity and a wide range of pore-size distribution.

获得了一系列具有几乎相同孔隙结构但表面化学性质不同的明确且均匀的孔隙结构 (WDUPS) 载体。这种方法可以有效地消除传统载体无法实现的孔结构效应。通过初湿浸渍将 Fe 引入所制备的 WDUPS 载体以获得 WDUPS Fe 基催化剂，用于研究载体对 Fischer-Tropsch 合成的影响。根据反应结果，WDUPS SiO ₂上负载的Fe ₂ O ₃表现出最高的CO转化率和C _2-4烯烃选择性。其他三种 WDUPS 催化剂，其载体为 WDUPS Al ₂ O ₃、TiO ₂和ZrO ₂有利于在费-托合成过程中形成C ₅₊烃。在使用WDUPS Al ₂ O ₃作为载体的Fe基WDUPS催化剂上可以获得最高的C ₅₊烃选择性。提出在这项研究工作中获得的载体对催化行为的影响比以前使用具有模糊弯曲度和宽范围孔径分布的常规载体获得的结果更可靠。
