CO-TPD and H2-TPD and CO/H2-TPSR were used to study the effect of the support on the performance of Fe-MnO catalysts in CO hydrogenation for the production of light olefins. It was found that a Fe-MnO/MgO catalyst (based on a basic support) is capable of strongly adsorbing CO and H2 favorable for the production of light olefins and CO conversion. A Fe-MnO/ Al2O3 catalyst (based on an acidic support) only showed strong adsorption of H2, but weaker adsorption of CO, and so, it was a poor catalyst for light olefins from syngas.
