제목 Effects of Mn promoter on mesoporous Fe2O3-ZrO2 bimetal oxides for CO hydrogenation to hydrocarbons
초록 The ordered mesoporous Fe2O3-ZrO2 at an optimal molar ratio of Zr/Fe at ~ 0.25 showed the highest catalytic activity by maintaining its original mesoporous structures even after the reductive Fischer-Tropsch synthesis (FTS) reaction conditions. The manganese (Mn) promoter has been generally known to increase the olefin selectivity by inhibiting the readsorption of olefin intermediates for a further hydrogenation to paraffinic hydrocarbons on the Fe-based FTS catalysts. On the Fe2O3-ZrO2, 5 wt%Mn revealed the highest catalytic activity and structural stability with higher olefin selectivity. To verify the effects of Mn promoter with their surface distributions, Mn promoter was incorporated by impregnation method on the pre-synthesized Fe2O3-ZrO2 (Mn/FeZr0.25Ox) as well as by tri-metal precursors incorporation method into the hard template of the KIT-6 mesopores (FeZr0.25Mn0.05Ox).
