Abstract
The effect of second metal component on the structural characteristic of Fe M UFP catalysts was investigated by in situ Mossbauer spectroscopy. The incorporation of second metal component hinders, the reduction and carburization of iron containing phase in the presence of H2 and CO, and the degree of hindrance is in the order of Mg Mn Zn due to the interaction between iron and the second metal component. Consequently, the formation of light olefinic products is in the order of Fe Mg>Fe−Mn·Fe−Zn catalysts consistent with the F-T synthesis performance.
