The kinetics of the Fischer-Tropsch synthesis reactions are studied in an internally recycled reactor over a commercial 0.5% Ru/..gamma..-Al/sub 2/O/sub 3/ catalyst. Steady-state turnover numbers are obtained for 3:1 and 2:1 H/sub 2//CO feed gas over a temperature range of 200-300/sup 0/C, a pressure range of 0.6-1.0 MPa, and a weight hourly space velocity range of 0.1-0.5 h/sup -1/. Intrinsic kinetic data are obtained on surface-impregnated catalyst. It is shown that even at the highest conversion levels, heat and mass transfer resistances are negligible. A mechanism for the Fischer-Tropsch synthesis is proposed and several kinetic models are developed. The kinetic model which best fit the experimental data is given. This model is based on the assumption that the rate-determining step is the hydrogenation of adsorbed CH /SUB x/ species. The product selectivity and CO conversion are strongly influenced by temperature.
