Mechanism and kinetics of CO hydrogenation over an iron catalyst to form paraffins and olefines

A kindle model for the CO hydrogenation reaction over Fe/Al2O3 catalyst, based on the mechanism of parallel formation of paraffins and olefines, has been proposed The model satisfactorily describes experimental data on the reaction mixture composition dependence of the rate of total CO conversion to hydrocarbons and of the paraffin selectivity. It was shown that in the case of olefines it is necessary to fake into consideration the consecutive steps of their hydrogenation, which significantly influence the reaction product distribution.
