Abstract

The addition of a small amount of SiO₂- to Al₂O₃-supported cobalt catalyst significantly increased the reduction degree of the supported cobalt oxides and the metallic cobalt surface area, as a result of remarkable enhancement of the Fischer-Tropsch synthesis (FTS) activity in the slurry-phase reaction. Properties of various catalysts were characterized by in situ DRIFT, XRD, TPR, N₂ physisorption and H₂ chemisorption. Furthermore, properties and reaction performances of the present catalyst system were compared with those of Al₂O₃-promoted Co/SiO₂ catalyst.
