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 availabilit...

Reactions of small molecules with transition metal nanoparticles have attracted considerable interest over the past decades since they can provide a conceptual framework for applications such as heterogeneous catalysis and hydrogen storage . The reaction of H2 and CO with Fe and Co nanoparticles has been widely studied due to the relevance to the Fischer-Tropsch process in which a mixture of H2...

Upgrading C1 chemicals (for example, CO, CO/H2, MeOH and CO2) with C-C bond formation is essential for the synthesis of bulk chemicals. In general, these industrially important processes (for example, Fischer Tropsch) proceed at drastic reaction conditions (>250 °C; high pressure) and suffer from low selectivity, which makes high capital investment necessary and requires additional purification...

The use of zeolite catalysts for the refining of products from methanol synthesis and Fisher-Tropsch synthesis was reviewed. The focus was on fuels refining processes and differences in the application to indirect liquefaction products was compared to petroleum, which is often a case of managing different molecules. Processes covered were skeletal isomerisation of n-butenes, hydroisomerisation ...

Fischer-Tropsch(FT) reaction involves the hydrogenation of carbon monoxide to hydrocarbons typically by group VIII metals [1]. Cobalt is one of the first metals used as FT catalyst and is typically mixed with Mn to promote carbon monoxide conversion to more valuable higher (C5+) hydrocarbons and olefins. The properties of metal catalysts can be controlled by fine-tuning chemical composition, su...
