In this study, the CHA shape zeolite was synthesized by a conventional hydrothermal method, and Co/γ-Al2O3 catalyst was prepared by a conventional impregnation method. The hybrid FTS catalyst was prepared by physically mixing Co based catalyst supported on synthesized zeolite and commercial zeolite. The effect of hybrid catalyst in syngas was investigated on conversion and selectivity. The physiochemical properties of the prepared catalysts were characterized by various characterization techniques. The catalytic performance of the bi-functional hybrid catalyst was investigated under a fixed bed reactor. The FTS products were analyzed by on-line and off-line GCs. The catalytic performance over the multi-functional hybrid FTS catalysts was compared with Co/γ-Al2O3 catalyst. It was found that the hybrid catalyst showed relatively lower alpha value and higher methane selectivity than the Co/γ-Al2O3 catalyst because synthesized zeolite has high acidity.
