| 英文摘要 | The effects of an improved dehydration way on structural properties and fischer-tropsch (f-t) synthesis performance of an iron-based catalyst were studied. the catalytic performance for f-t synthesis was investigated in a continuous stirred tank slurry reactor (cstr) under the reaction conditions of n(h(2))/n(co) = 0.67, whsv = 1000 h(-1), p = 1.5 mpa, and t = 250 degrees c. the structural properties of the catalysts were characterized by n(2) physical adsorption, x-ray diffraction, inductively coupled plasma atomic emission spectroscopy, x-ray photoelectron spectroscopy, nh(3) temperature-programmed desorption, mossbauer spectroscopy, and high-resolution transmission electron microscopy the results showed that the bet surface area and alpha-fe(2)o(3) dispersion were increased, and the particle size and the surface sio(2)/fe ratio of the catalyst were decreased after water pretreatment and twice drying. the catalyst exhibited high f-t synthesis activity. moreover, the hydrocarbon selectivity shifted to lower carbon numbers for the catalyst underwent the improved dehydration way, ascribing to its increased surface acidity. |
