Title: Kinetics of the Fischer-Tropsch reaction on a precipitated promoted iron catalyst. 1. Experimental procedure and results

Abstract

The Fischer-Tropsch reaction on a commercial promoted precipitated iron catalyst was studied in a tubular reactor under non-deactivating conditions of temperatures between 523 and 623 K, pressures between 0.6 and 2.1 MPa, hydrogen to carbon monoxide feed ratios between 3.0 and 6.0 mol/mol, and W/F[degree][sub CO] values between 9.2 and 63.0 kg[center dot]s/mol. The selectivity for carbon dioxide, methane, and hydrocarbons of different functionality with 2-15 carbon atoms in the molecule was obtained as a function of the carbon monoxide conversion, the reactor temperature, and the total pressure. The initial rate of formation of these products was measured as a function of the total pressure and the partial pressures of hydrogen and carbon monoxide at the reactor inlet. These experiments, combined with the information gained from the catalyst characterization, indicated that carbon dioxide is formed by the water gas shift reaction. Methane, n-paraffins, and 1-olefins with two and more carbon atoms in the molecule are all primary products of the Fischer-Tropsch reaction. The composition of the hydrocarbon product fraction, as a function of the number of carbon atoms in the hydrocarbon molecule, could be described by the Schulz-Flory distribution, although it is shown that the latter only approximately holds formore » the effluent of an integral reactor.« less
