ABSTRACT:

The steady-state activity and selectivity of iron-based catalysts in the Fischer-Tropsch synthesis is governed by complex interactions between the reactants and reaction intermediates on the catalyst surface, the bulk carbidic and oxidic phases formed during synthesis, carbonaceous deposits on the surface, and the promoter compounds present as part of the catalyst composition. Improvements in activity and shifts in selectivity can be obtained by incorporating promoters. However, the understanding of the interplay between promoters and other catalyst constituents is not well-developed. Further research on this is recommended.
