Fischer-Tropsch synthesis in a static catalyst bed and in a three-phase system in the presence of composite materials containing iron and cobalt particles in the nano-size range 30-60 nm is investigated. It is shown that in both process implementation methods the yield and selectivity of liquid hydrocarbon formation increase with iron content in the composite material. In this case, the catalysts exhibit higher activity in the static bed and greater selectivity in the three-phase system. In the static bed of the most active catalyst containing 44.4 % iron and 33.3 % cobalt, the yield of C5+ hydrocarbons was 103 g/m(3).
