ABSTRACT:

A Co/MgO/SiO(sub 2) Fischer-Tropsch catalyst was operated simultaneously with a Cu/ZnO/Al(sub 2)O(sub 3) water-gas-shift catalyst in a slurry reactor for over 400 hours. The process conditions were held constant at a temperature of 240(degrees)C, a pressure of 0.79 MPa, and a 1.1 H(sub 2)/CO feed of 0.065 Nl/min-g.cat. The Fischer-Tropsch activity remained constant at the level predicted by the operation of the Co/MgO/SiO(sub 2) catalyst alone. The water-gas-shift reaction was near equilibrium. The hydrocarbon product distribution of the combined catalyst system was stable and matched that of the CO/MgO/SiO(sub 2) operating alone under similar conditions. The combined catalyst system exhibited a high selectivity to n-alkanes. Neither catalysts's operation appeared to have a detrimental effect on that of the other, showing promise for future option.
