Abstract

The synthesis of Fischer-Tropsch 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. Our cobalt catalyst was prepared Co/alumina, Co/silica and Co/titania by the incipient wetness impregnation of the nitrates of cobalt with supports. Co-based catalysts was calcined at $400^{\circ}C$ before being loaded into the FT reactors. After the reduction of catalyst has carried out under $450^{\circ}C$, FT reaction of the catalyst has carried out at GHSV of 4,000 under $200^{\circ}C$ and 20atm. From test results, the order of increasing activity for the catalyst was Co/alumina > Co/silica > Co/titania. When the content of Co metal such as 5, 12, 20 and 30wt% was changed, an CO conversion increased as the content of Co metal increased. The activity of catalyst has obtained the best value at 12wt% Co content.
