dc.description.abstractCO2 hydrogenation to light olefins over Fe-Co-Zn/K-Al2O3 catalysts with different Zn loading contents (0�1.74 wt%) is studied. The addition of Zn improves the dispersion and the reducibility of iron oxides. The amount of CO adsorbed of the catalysts showed a volcanic trend as a function of Zn content with its maximum of 2.42 ?mol g?1 at 0.58 wt% Zn, suggesting an increase of number of active sites. The 0.58 wt% Zn-promoted Fe-Co/K-Al2O3 catalyst shows superior activity for light olefins yield (19.9%) under the optimum operating conditions of 340 �C, 25 bar, 9,000 mL gcat?1 h?1 and H2 to CO2 ratio = 4. A gradual decrease in olefin to paraffin ratio with an almost constant CO2 conversion as a function of time-on-stream is observed, which is related to a continuous increase of iron carbide content, indicating that the iron carbide can be acted as the active site for paraffins production. � 2021 Elsevier Ltden_US
