Physico-chemical properties of precipitated iron-based catalystswith and without SiO2 for the Fischer-Tropsch synthesis |
| 초록 |
Iron-based catalysts have received much attention as catalysts for the Fischer-Tropsch synthesis (FTS) due to their high activity, low cost, and potential activity for the water-gas shift reaction. Various chemical and structural promoters such as SiO2, Cu, and K2O have been used to improve the catalytic performance of precipitated iron catalysts. In this study, we investigated the physico-chemical properties of precipitated iron-based catalysts with and without SiO2 addition. The catalysts with SiO2 were prepared by two comparative ways, i.e., incorporation of SiO2 before precipitation (denoted as precipitated SiO2) and after precipitation (denoted as binder SiO2), respectively. Catalyst characterization revealed that the catalysts with precipitated SiO2 showed the higher dispersion of catalysts and/or promoters than the catalysts with binder SiO2 and those without SiO2. In terms of surface basicity, the catalysts without SiO2 showed higher value than those with SiO2. |
