摘要	Zr, Ca and Mn promoted Co/SiC catalysts have been prepared with constant loadings of 15 wt% Co and 5 wt% Zr or Ca or Mn and investigated for the Fischer-Tropsch synthesis. It was revealed that the crystallite size of Co3O4 increased from 15 to 37, 22, 16 nm and the corresponding Co-0 dispersion decreased from 8.3 to 3.5, 5.8 and 7.8% with the addition of Zr, Ca or Mn promoter. The large crystallite size and outer surface location of Co species for the Co/Zr/SiC could account for the low interaction between Co and SiC support, which led to the easy reduction. Compared to the CO conversion (71%) of Co/SiC catalyst, it increased to 82 and 80% for the Co/Zr/SiC and Co/Mn/SiC catalysts, whereas it declined to 13% for the Co/Ca/SiC catalyst. Furthermore, the product distribution took a different trend: it was shifted towards the products of long chain hydrocarbons (C-5-C-22) for Co/Zr/SiC and Co/Mn/SiC catalysts, however, light products (methane and C-2-C-4) were the major products for the Co/Ca/SiC catalyst.
