Hydrocarbon formation model of slurry-phase Fischer-Tropsch synthesis Conference Paper uri icon

abstract

  • Hydrocarbon formation rates of Fischer-Tropsch synthesis are modeled using three different approaches. The three proposed models provide predictions of concentrations of linear paraffins and linear 1- and 2-olefins. The models assume that the chain growth initiates on an active sites of the catalyst by hydrogenation of adsorbed monomer to adsorbed methyl group. All models assume that the 1-olefin can re-adsorb and form the adsorbed alkyl species, which can subsequently propagate or terminate. For all model parameters, non-negative values are obtained. The best fit of experimental data is obtained for the Nowicki's model, and the worst is for the "olefin re-adsorption product distribution model" (ORPDM). However, the differences in predictions between these models are < 6%, thus, the ORPDM may be considered as the most preferred model due to its simplicity (lower number of kinetic parameters). This is an abstract of a paper presented at the 18th International Congress of Chemical and Process Engineering (Prague, Czech Republic 8/24-28/2008).
