| 英文摘要 | Two spherical fe/cu/k/sio2 catalysts with different preparation scale for slurry fischer-tropsch (ft) synthesis were prepared by a combination of co-precipitated and spray drying method. the pellet size of the catalyst with a laboratory scale is 5-15 mu m, whereas that is 40-60 mu m for the scaled-up catalyst. n-2 physical adsorption, h-2 temperature-programmed reduction, co2 temperature-programmed desorption, mossbauer spectroscopy, and x-ray diffraction were used to characterize the textural properties, reduction and carburization behavior, and phase transformation of the two catalysts. the results show that the scaled-up catalyst has larger crystallize size and pore volume, lower bet surface area, and lower surface basicity than the laboratory-scale catalyst. moreover, the scaled-up catalyst was more difficult to be reduced and carburized. however, the results of ft synthesis in a slurry bed indicate that the scaled-up catalyst exhibits comparative activity, better reaction stability, and higher selectivity for olefin and heavy hydrocarbons. scanning electron microscopy results suggest a better attrition resistance of the scaled-up catalyst during the ft reaction tests. |
