Generalized kinetic model for iron and cobalt based Fischer–Tropsch synthesis catalysts: Review and model evaluation

Abstract During the decades of kinetic studies over iron and cobalt based Fischer–Tropsch synthesis (FTS) catalysts, various mechanisms and equations have been proposed with a wide diversity. Literature review indicates that neither general kinetic model nor the same shape for reaction rate equation has been proposed for FTS. In the present paper, a generalized mechanism was developed and verified against reported kinetic data for both iron and cobalt based FTS catalysts. Also it was shown that all various types of the proposed mechanisms can fall under the heading of one general mechanism. The proposed generalized macro kinetic model can be applied simultaneously to both iron and cobalt based FTS catalysts.
