Product distribution and reaction pathways during Fischer-Tropsch synthesis on an iron catalyst Conference Paper uri icon

abstract

  • A precipitated iron Fischer-Tropsch (F-T) catalyst was tested in a stirred tank slurry reactor under different process conditions. The extent of water-gas-shift (WGS) reaction increased with increase in conversion of the limiting reactant, indicating that the WGS is a consecutive reaction with respect to water formed in the F-T synthesis reaction. The experimental results indicate that 1-olefins participate in secondary reactions (e.g. 1-olefin hydrogenation, isomerization and readsorption). Secondary hydrogenation and isomerization of 1-olefins increased with increase in partial pressure of hydrogen. Gas residence time had significant effect on selectivity of ethylene and other gaseous 1-olefins. Chain growth probability factor increased with increase in molecular weight.
