In this paper, the development of research on the water gas shift(WGS) reaction in the Fischer-Tropsch synthesis (FTS) was reviewed. The WGS reaction is important when synthesis gas with nonstoichiometric amounts of hydrogen is used, whereas CO efficiency is decreased accordingly. Its thermodynamic analysis, reaction mechanism and kinetics in conjunction with the FTS are presented. The WGS reaction is equilibrium or close to equilibrium reaction under Fischer-Tropsch conditions on catalysts with a high water gas shift activity such as iron-based FTS catalysts, which may operate via a mechanism with a formate species or via a direct oxidation mechanism. The kinetic studies assumed that the WGS reaction proceeds on a different catalytic site than the FTS. The effects of catalyst preparation and operation parameters on the WGS reaction activity are also summarized. The importance and prospect of research on the WGS reaction under the Fischer-Tropsch conditions are proposed.
