| 英文摘要 | the effects of support pretreatment with nc(1)-c-5 alcohols on the performance of rh-mn-li/sio2 catalyst in the synthesis of c-2-oxygenates from syngas have been investigated by co hydrogenation reaction, transmission electron microscopy (tem), pulse adsorption of co and h-2, and fourier transform infrared (ft-ir) spectroscopy. the catalysts prepared from the pretreated silica supports exhibited higher space time yields of c-2-oxygenates (styc2-oxy) and selectivities towards c-2-oxygenates (sc2-oxy) than that prepared from the untreated silica support. the enhancement in the hydrophobicity of the pretreated silica supports would be favorable for increasing rh dispersion and ratio of rh+/rh-0 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. |
