Active phases for high temperature Fischer-Tropsch synthesis in the silica supported iron catalysts promoted with antimony and tin

Fischer-Tropsch synthesis provides an important opportunity for utilization of biomass and plastic waste. Iron catalysts are the choice light olefin using reaction. In this paper, we investigate strong promoting effects antimony tin on catalytic performance silica supported iron a combination advanced in-situ techniques. The catalyst doping with these elements added via impregnation results in major increase reaction rate much better stability. No enhancement dispersion was observed after promotion, while somewhat higher extent carbidization promoted catalysts. Iron-bismuth bimetallic nanoparticles detected by several working catalysts, promoters located close proximity to nanoparticles. promotion leads 7–10 times intrinsic activity surface sites due their interaction promoters.
