Abstrakt:	Abstract: Fischer–Tropsch (FT) synthesis reaction was performed using ferrihydrite catalyst. During 100h of FT synthesis reaction, composition changes of the reaction product were studied according to the reaction time using an on-line GC, and the final FT products collected in traps were analyzed by GC–MS. Also, an effect of gas feed ratio of H2/CO on the selectivity of the synthetic products was studied. As a H2/CO feed ratio increased, not only CO conversion and activity of catalyst improved two times, but also CO2 conversion was reduced by approximately 40% thereby improving the efficiency of catalyst significantly.
