Abstract: 

The iron-based catalyst was prepared by a microemulsion method. The composition of the final nanosized iron catalyst, in terms of the atomic ratio, contains 100Fe/4Cu/2K. The experimental techniques of XRD, BET, TEM, and TPR were used to study the phase, structure, and morphology of the catalyst. Fischer-Tropsch synthesis (FTS) reaction test was performed in a fixed bed reactor under pressure of 17 bar, temperature of 270-310 oC, H2 to CO ratio of 1, and a Gas Hourly Space Velocity (GHSV) of 3 nl.hr-1.gCat-1. The temperature of the system as a key parameter was changed and its effect on the selectivity and reaction rate was analyzed. The results show that the rates of both reactions including FTS and water-gas shift (WGS) raised by increasing temperature. For this condition, CO conversion was also increased up to 87.6%.
