Fischer-Tropsch synthesis (FTS) reaction for the direct production of gasoline range hydrocarbons (C₅-C₉) from syngas was investigated on Ru, Pt, and La promoted Co/ZSM-5 (Si/Al = 25) catalysts. The hybrid catalysts were characterized by BET surface area, XRD, H₂-TPR, NH₃-TPD and XPS analyses. These physico-chemical properties were correlated with activity and selectivity of the catalysts. The promoted Co/ZSM-5 hybrid catalysts were found to be superior to the unpromoted Co/ZSM-5 catalyst in terms of better C₅-C₉ selectivity. Pt-Co/ZSM-5 exhibited the highest catalytic activity because of the small cobalt particle size.
