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 483–513 K,
pressure of 8 bar, H2/CO feed ratio of 1–3, and space velocity of 2700–5200 h-1. The optimal amount
of catalyst containing 15wt.%Co/10wt.%K/Al2O3 was prepared using impregnation procedure. The
combined enol/carbide mechanism as the rate-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 111.5 kJ/mol and 100 kJ/mol, respectively.
