摘要	A series of Cu-Fe-Co based catalysts with different mass fractions of Fe and Co were prepared by co-impregnation method. The catalytic performances of the catalysts for mixed alcohols synthesis from carbon monoxide hydrogenation were investigated in a fixed bed flow reactor. The samples were characterized by Brunauer-Emmett-Teller (BET), X-ray diffraction (XRD), X-ray photoelectron spectroscopy (XPS), field-emission scanning electron microscope (FE-SEM), and H-2 temperature-programmed reduction (H-2-TPR). The results showed that the addition of a suitable content of Co to the Cu-Fe based catalyst significantly improved the space-time yield (STY) and CO conversion while alcohol selectivity was constant. For the catalyst with a mass fraction of Cu, Fe, and Co of 25%, 22%, and 3%, respectively, a STY of 205.6 g.kg(-1)h(-1) and CO conversion of 56.6% were obtained. The XRD, XPS, and TPR results showed that when the Cu content was unchanged, the introduction of some Co contributed to the formation of a small quantity of the CuFe2O4 phase on the surface of catalysts, which promoted the interaction between Cu and Fe, improved the dispersion of active components and enhanced the catalytic activity and STY of the mixed alcohols. With an increase of the Co content in the catalyst, the interaction between the metallic components was transformed and the Cu-Co spinel phase was generated, leading to a slight decrease of alcohol selectivity.
