Enhanced performances of Fischer-Tropsch catalysts modified with Re as a promoter and supported on various structured materials

Abstract This paper presents enhanced performances of Fischer-Tropsch (F-T) catalysts modified with Re as a promoter and supported by various structured materials. The traditional Fe-Co based catalyst was prepared the simultaneous impregnation then application wash-coating slurry method to coat on materials, including monolith metallic foams. Their physicochemical properties were characterized Brunauer–Emmett–Teller specific surface area, hydrogen temperature programmed reduction. reaction carried out at 250°C, pressure 20 bar, GHSV 3600 mL.g −1 .h . It has been shown that efficiency F-T synthesis is significantly improved both modification material its catalyst. interesting resulted in decreasing gas formation improving C 5+ yield. In presence catalytic promoter, CO conversion yield increased 49% 50%, respectively. Furthermore, materials brought further enhancement performance an additional 23% increase All have observed be stable during 24 hours stream.
