The synthesis of Fischer-Tropsch (FT) oil is the catalytic hydrogenation of CO to give a range of products, which can be used for the production of high-quality diesel fuel, gasoline and linear chemicals. 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 before being loaded into the FT reactors. After the reduction of catalyst has been carried out under for 24h, FT reaction of the catalyst has been carried out at GHSV of 4,000/hr under and 20atm. From these experimental results, we have obtained the results as following; In case of catalysts, the activity of 12wt% synthesized by organic solvent was about 2 or 3 times higher than the activity of 12wt% catalyst synthesized without organic solvent. In particular, the activity of the catalyst prepared in the presence of an organic solvent P was two to three times higher than that of the 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 catalyst prepared in the presence of an organic solvent of Glyoxal solution.
