ABSTRACT:
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.
