Synthesis of nano-sized Co-Pt/Tio2 catalysts for Fischer- Tropsch reaction

The best catalysts in the Fischer- Tropsch synthesis is the cobalt based catalys In this research, Cobalt catalyst was due to its activity, selectivity, and lifetime. made on the basis of Titana and Platinum promotion, some of Cobalt catalyst was made with Platinum promotion in 5 weight percent such as (wt%10wt%15wt%20 ،wt%25wt%30) with Co-precipitation method . After synthesis of catalyst, morphology of it was investigated with SEM1, XRD2, TPR3 methods. Specific area of catalyst was determined with BET4 method and compared to other catalysts of cobalt with different weight percents. According to result, increaseing in weight percent of cobalt result in decrease of temperature reduction then reduce catalyst activity. Because of filling the pores with cobalt particles, specific area and pore volume of catalyst were reduced.
