The Fischer-Tropsch synthesis with a mechanical mixture of a cobalt catalyst and a copper-based water gas shift catalyst

The feasibility of using a mechanical mixture of a Co/MgO/SiO 2 Fischer-Tropsch catalyst and a Cu-ZnO/Al 2 O 3 water gas shift (WGS) catalyst for hydrocarbon synthesis in a slurry reactor has been established. Such a mixture can combine the superior product distribution from cobalt with the high activity for the WGS reaction characteristic of iron. Weight ratios of Co/MgO/SiO 2 to Cu-ZnO/Al 2 O 3 of 0.27 and 0.51 for the two catalysts were studies at 240 o C, 0.79 MPa, and in situ H 2 /CO ratios between 0.8 and 3.0. Each catalyst mixture showed stable Fischer-Tropsch activity for about 400 h on stream at a level comparable to the cobalt catalyst operating alone
