Hydrogenation of CO on Cobalt Catalyst in Fischer-Tropsch Synthesis

Mohsen Mansouri, Hossein Atashi, Ali A. Mirzaei and Masoud Karimi

The kinetic experiments of Fischer–Tropsch synthesis (FTS) over an industrial Co/K catalyst are carried out in a micro-fixed-bed reactor under the conditions as follows: temperature of 483–513K, pressure of 8bar, H2/CO feed ratio of 1–3, and space velocity of 132700–5200h-1. The optimal amount of catalyst containing 15wt.%Co/10wt.%K/Al2O3was prepared using impregnation procedure.The combined enol/carbide mechanism as the rate-p controlling step gives the most plausible kinetic model among the nine different models tested.The activation energies for optimal kinetic model and power law equation were obtained 111.5kJ/mol and 100 kJ/mol, respectively.
