In the GTL process, Fischer-Tropsch synthesis (FTS) reaction is known as a key catalytic process that converts synthesis gas (CO + H2) to value-added hydrocarbon products. The CO2 utilization in FTS process takes the possibility to reduce the greenhouse gases and utilizes the captured CO2 in an economic and environmentally-friendly way. In this study, the zeolite was synthesized by a conventional hydrothermal method, and Co/γ-Al2O3 catalyst was prepared by an impregnation method. The cobalt based hybrid FTS catalyst was prepared by physically mixing Co/γ-Al2O3 with zeolite. The effect of CO2 ratio in syngas was investigated on conversion and selectivity. The physiochemical properties of all prepared catalysts were characterized by XRD, BET and NH3-TPD techniques. The catalytic performance of the physically mixed bi-functional hybrid catalyst was evaluated under a fixed bed reactor. The products were analyzed by on-line and off-line GCs. The catalytic performance over the bi-functional hybrid FTS catalysts was compared with Co/γ-Al2O3 catalyst. Keywords: GTL, Fischer-Tropsch Synthesis, FTS, Zeolite
