The FT synthesis (FTS) of syngas, whose composition was H_2:CO:N_2 = 2:1:3 (volumetric ratio), was carried out using Co-based catalysts in order to produce hydrocarbons (HCs) equivalent to kerosene, which is used as an alternative aviation fuel. The FTS had been conducted in a downdraft continuous-flow-type fixed bed reactor under a temperature of 503 K and a pressure of 3.0 MPa for 5 h. The effects of the space velocity (W/F) and the chelator on the FTS were studied by focusing on primary kerosene yield and the carbon mass balance. In C6+ HCs, the selectivity of CO to the C11-C14 HCs equivalent to kerosene was found to be the second highest, the highest being its selectivity to C6-C10 HCs equivalent to gasoline. The amount of primary kerosene produced was maximum (the overall CO conversion was 99% and the selectivity to C11-C14 HCs was 10%) under the W/F of 9 g h/mol. The decrease of W/F in the FTS deceased the overall CO conversion. The addition of a chelator decreased the selectivity to CO_2.
