| 摘 要： | 采用化学还原法在乙二醇/水混合溶剂中制备纳米Fe-Mn催化剂,考察其在液态聚乙二醇中的F-T合成反应性能。透射电子显微镜、X射线衍射、穆斯堡尔谱和X射线光电子能谱等表征结果表明,纳米Fe-Mn催化剂粒径为(20~50)nm,具有铁磁性非晶结构,Mn主要富集在催化剂表面,Mn的加入使Fe更富电子,催化剂更易碳化。纳米Fe-Mn催化剂表现出很高的F-T反应活性,Mn的加入有利于催化剂的链增长反应,使产物分布向重质烃方向偏移。

| Abstract: | An iron-manganese(Fe-Mn) nanocatalyst for Fischer-Tropsch synthesis(FTS) was prepared by the chemical reduction method in ethylene glycol/water and tested directly in liquid polyethylene glycol(PEG) phase.Transmission electron microscopy,X-ray diffraction,Mössbauer spectroscopy,and X-ray photoelectron spectroscopy results indicated that the reduced catalyst had ferromagnetic amorphous alloy structure with particle size in the range of (20-50) nm.The addition of Mn enriched in surface led to electron-richer iron sites which were favorable for the carburization.The Fe-Mn nanocatalyst exhibited excellent FTS activity.The addition of Mn enhanced the chain growth reaction and increased the selectivity to heavy hydrocarbons. |
