| 中文摘要 | the effects of support pretreatment with normal c1-c5 alcohols on the performance of rh-mn-li/sio2 catalyst in the synthesis of c2-oxygenates from syngas have been investigated by co hydrogenation reaction, transmission electron microscopy (tem) and fourier transform infrared (ft-ir)spectroscopy.the catalysts prepared from the pretreated silica supports exhibited higher space time yields of c2-oxygenates(styc2-oxy) and selectivities towards c2-oxygenates(sc2-oxy)than that prepared from the untreated silica support. the enhancement in the hydrophobic properties of the pretreated silica supports would be favorable for increasing rh dispersion and ratio of rh+/rho sites, therefore increasing the number of active sites,especially the active sites for co insertion. such variations are responsible for the improvements in the catalytic performance of the rh-mn-li/sio2 catalyst. |
