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.
