Fischer Tropsch Reaction is one of many solutions that can be used to solve fuel shortage by synthesizing liquid fuel from synthetic gas (syngas). Catalyst is the key of Fischer-Tropsch reaction that regulate the reaction rate and selectivity so it is a need to develop an active and selective catalyst. The research aim was to develop iron based Fischer-Tropsch catalysts via 2 synthesis routes. In the first route, catalyst supports (CeO2/Al2O3) were synthesized using hydrothermal method followed by impregnation of Fe(NO3)3, while in the second route, the whole catalysts were synthesized in 1 step using hydrothermal method. The synthesized Fe2O3/CeO2/Al2O3 catalyst had weight ratio of 10:5:85 with surface area reached 94,3 m2/g based on Energy Dispersive X-Ray (EDX), X-Ray Fluorescence (XRF), and Brunauer-Emmett-Teller (BET) method surface area analysis results, respectively. The Scanning Electron Microscope (SEM) showed that the catalysts had rod structures with diameter of 300-700 nm and 5-10?m long. The X-Ray Diffraction (XRD) diffractograms showed the formation of ?-Al2O3 at calcination temperature of 900 oC, while the Temperature Programmed Reduction and Desorption (TPR/TPD) showed the catalysts reduction temperature by H2 were at the range of 300-600 oC.
