Iron-cobalt catalyst, manufacturing method same and method for obtaining water-gas shift reaction activity and for highly selective liquid fuel production in Fischer-Tropsch synthesis using iron-cobalt catalyst

摘要

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-coba and a step of reducing the iron-cobalt under a hydrogen atmosphere.
