Fischer-Tropsch (FT) has a long industrial history of producing high-quality fuels. Lowtemperature FT (LTFT) is considered in this work. This is because FT reaction is highly exothermic, and a lower temperature can improve the final conversion regarding the thermodynamic equilibrium. For LTFT, the desired syngas ratio falls in the range of 2 -2.2 for H2 : CO, and the reaction temperature is reported to range from 200 to 270 ℃ 6, 8, 9 as well as pressure in 15 -50 bar.
