This paper reports on Fe-Co bimetallic catalysts that are active and selective for synthesis of olefin-rich C2+ hydrocarbons from CO2 hydrogenation. The combination of Fe and a small amount of Co led to a dramatic bimetallic promotion of C2+ hydrocarbons synthesis in CO2 hydrogenation on Fe-Co/Al 2O3 catalyst with 15 wt% total metal loading. The addition of K to Fe-Co/Al2O3 catalyst further improved the formation rate of C2+ hydrocarbons as well as their olefin contents, while it suppressed CH4 formation significantly. Olefin-rich C2+ hydrocarbons was successfully synthesized using K-promoted Fe-Co/Al2O3 catalysts with high K loadings (Co/(Co + Fe) = 0.17 atom atom-1, K/Fe ≥ 0.5 atom atom-1) using CO2 as a carbon source.
