The Reaction Kinetics of a Fischer-Tropsch Synthesis Over a Commercial Eggshell Co/SiO₂ Catalyst

Abstract

The comprehensive kinetic model of Fischer-Tropsch synthesis over a commercial eggshell Co/SiO₂ catalyst in a fixed-bed reactor was investigated experimentally. This model was expressed in the combination of kinetic rate of CO consumption and the equation of the growth probability factor α was obtained. Through parameter evaluation and optimization, both the rate of CO consumption was given and the equation of a was obtained. It was also proved that the proposed model could predict the kinetic rate of CO consumption and the product distributions well. The appropriate operating conditions for this catalyst were concluded by the model and they were in good agreement with the results in the industrial pilot-scale research.
