Formation of High‐Molecular Hydrocarbons by CO‐Based Fischer‐Tropsch Synthesis Using Na‐Promoted Fe Catalysts

open access: yesChemCatChem, Volume 17, Issue 7, April 4, 2025.
Na‐promoted Fe catalysts are investigated to produce high‐molecular hydrocarbons using the CO‐based Fischer–Tropsch synthesis. Highest hydrocarbon formation rates occur in the inlet part of the catalyst due to the substantial presence of Fe carbides. The Fe carbides react with the formed water to produce FT‐inactive Fe3O4 along the reactor.
