摘要
The addition of small amount of TiO2 to silica-supported cobalt catalysts significantly increasing the dispersion of cobalt and Co metallic surface area resulting in the remarkable enhancement of the Fisher-Tropsch synthesis (FTS) activity in the slurry-pliase reaction. The addition of TiO2 adjusted the interaction between cobalt and silica support quite well to realize the favorite dispersion and reduction degree of supported cobalt, leading to high catalytic activity in FTS. The properties of various catalysts were characterized by in-situ DRIFT, XRD, TPR, N-2 physisorption and H-2 chemisorption. (c) 2007 Elsevier B.V. All rights reserved.
