Recent Mechanistic Understanding of Fischer-Tropsch Synthesis on Fe-Carbide

With an increase in energy consumption globally, Fischer-Tropsch (FT) synthesis is a good alternative for producing fuels and chemicals from coal, natural gas or biomass. Among them, coal to liquids has been put into production countries that have large reserves. In this process, Fe-based catalysts are commonly used due their earth abundance, comparatively wide operation range ready availability handle low H2/CO ratio coal. Despite extensive applications, the kinetic mechanistic understandings of Fe carburization FT reaction on Fe-carbides relatively limited complexity phase composition applied catalysts. This review summarizes current state knowledge Fe-carbide with emphasis underlying mechanism. Specifically, employment model catalyst, such as Raney Fe, could provide convenient way furnish information regarding subsequent reaction. A major challenge further understanding catalytic reactions occurring at surface correlating activity selectivity specific active site. To address issue, advancements both DFT calculations science techniques highly demanded.
