Abstract:
PURPOSE: A method for preparing iron-cobalt composite catalyst and a method for implementing water-gas shift reaction activity in Fischer-Tropsch synthesis and producing highly selective liquid fuel using the same are provided to enhance the yield of liquid. CONSTITUTION: A method for preparing iron-cobalt composite catalyst comprises: a step of supporting 5-20 parts by weight of cobalt with respect to 100 parts by weight of an iron catalyst(S140); and drying the supported iron-cobalt at 100-150 deg.C. for 3-5 hours(S150). The method further comprises a step of plasticizing the iron-cobalt; and a step of reducing the iron-cobalt under a hydrogen atmosphere.

Abstract:
PURPOSE: A two stage F-T reactor system for improving the conversion ratio of synthetic gas is provided to maximize the yield of synthetic fuel for extending the lifetime of a catalyst. CONSTITUTION: A two stage F-T reactor system for improving the conversion ratio of synthetic gas includes a first reactor(10) and a second reactor(20). The first reactor receives first synthetic gas containing H2 and CO in a composition ratio of 0.6-1.2, and controls the flow speed of the first synthetic gas, the internal temperature, and the pressure for securing the 50-80% of CO conversion ratio. The second reactor receives second synthetic gas containing H2 and CO in a composition ratio of 1.8-2.0, and controls the flow speed of the second synthetic gas, the internal temperature, and the pressure for securing the 90-95% of CO conversion ratio.
