Studying the Influence of the Preparation Procedure on the Stability of Titania-supported Co-Fischer-Tropsch Catalysts

Co/TiO₂FT-catalysts were prepared using Incipient Wetness Impregnation (IWI) and Homogeneous Deposition Precipitation (HDP). For all catalysts TEM and H₂-chemisorption show similarly sized supported nanoparticles. For IWI-catalysts clustering was observed. HDP-catalysts showed a more homogeneous distribution. The better distribution lead to higher cobalt time yields at comparable C₅₊-selectivities of 85-90%.
