Four metals are active as catalysts for the Fischer–Tropsch process: iron, cobalt, nickel, and ruthenium.Since FT process typically transforms inexpensive precursors into complex mixtures that require further refining, FT catalysts are based on inexpensive metals, especially iron and cobalt. Nickel generates too much methane, so it is not used. Typically, such heterogeneous catalysts are obtained through precipitation from iron nitrate soluti… WebFischer-Tropsch Technology. M.E. Dry, A.P. Steynberg, in Studies in Surface Science and Catalysis, 2004 4.3 Gas loop for LTFT synthesis using iron catalysts.
