| 英文摘要 | The metal-silica interaction and catalytic behavior of cu-promoted fe-mn-k/sio2 catalysts were investigated by temperature-programmed reduction/desorption (tpr/-tpd), differential thermogravimetric analysis, in situ diffuse reflectance infrared fourier transform analysis, and mossbauer spectroscopy. the fischer-tropsch synthesis (fts) performance of the catalysts with or without copper was studied in a slurry-phase continuously stirred tank reactor. the characterization results indicate that several kinds of metal oxide-silica interactions are present oil fe-mnk/sio2 catalysts with or without copper, which include iron-silica, copper-silica, and potassium-silica interactions. in addition to the well-known effect of cu promoter on casing the reduction of iron-based fts catalysts, it is found that cu promoter call increase the rate of carburization, but does not vary the extent of carburization during the steady-state fts reaction. the basicity of the cu and k co-promoted catalyst is greatly enhanced, as demonstrated by co2-tpd results. in the fts reaction, cu improves the rate of catalyst activation and shortens the induction period, whereas the addition of cu has no apparent influence on the steady-state activity of the catalyst. promotion of cu strongly affects hydrocarbon selectivity. the product distribution shifts to heavy hydrocarbons, and the olefin/paraffin ratio is enhanced on the catalyst due to the indirect enhancement of surface basicity by the copper promotion effect.
