摘要

CH3-modified Co/Ru/SiO_2 catalysts were prepared and the catalytic performances for Fischer-Tropsch synthesis were investigated. The modified and unmodified catalysts were characterized by FT-IR, N_2 physisorption, TG, XRD, TPR and DRIFTS. FT-IR indicated an effective surface organic modification. TG suggested that modified catalysts had good thermal stability. XRD and TPR showed that modified catalysts had similar reducibility and Co_3O_4 particle size with unmodified catalyst. During reaction tests in a fixed bed reactor it was found that compared with unmodified Co/Ru/SiO_2 catalyst CH_3-modified Co/Ru/SiO_2 catalysts showed higher selectivity to C_5-C_(11) hydrocarbons, which should be ascribed to hydrophobic surface of CH_3-modified Co/Ru/SiO_2 catalysts.
