This studied catalyst was prepared Cobalt-supported alumina and silica by the incipient wet impregnation of the nitrates of cobalt, promoter and organic solvent with supports. Cobalt catalysts were calcined at 350°C before being loaded into the FT reactors. After the reduction of catalyst has been carried out under 450°Cfor 24h, FT reaction of the catalyst has been carried out at GHSV of 4,000/hr under 200°C and 20atm. From these experimental results, we have obtained the results as following; In case of SiO2 catalysts, the activity of 12wt% Cobalt-SiO2 synthesized by organic solvent was about 2 or 3 times higher than the activity of 12wt% Cobalt-SiO2 catalyst synthesized without organic solvent. In particular, the activity of the Cobalt-SiO2 catalyst prepared in the presence of an organic solvent P was two to three times higher than that of the Cobalt-SiO2 catalyst prepared without the organic solvent. Effect of Cr and Cu metal as a promoter was found little. 200 h long-term activity test was performed with a Co/SiO2 catalyst prepared in the presence of an organic solvent of Glyoxal solution.
