Аннотация:High-temperature Fischer−Tropsch synthesis represents a
sustainable alternative for direct light olefin synthesis from syngas derived from
fossil and renewable feedstocks. It is found that the promotion of iron catalysts
with metals used for soldering (Bi and Pb) results in a remarkable increase in the
light olefin production rate with a possibility to conduct Fischer−Tropsch
synthesis at low reaction pressure. A combination of characterization techniques
uncovered notable migration of the promoting elements during the reaction and
decoration of iron carbide nanoparticles with the promoters. The promoters
seem to facilitate CO dissociation by removing O atoms from iron carbide.
