Effects of CO/CO2 ratio in synthesis gas on coke formation of K/Fe-Cu-Al Fischer-Tropsch catalyst |
| 초록 |
The coke formation has been investigated with varying CO/CO2 ratio in feed gas on a K/Fe-Cu-Al catalyst during Fischer–Tropsch (FT) synthesis. The K/Fe-Cu-Al catalyst was prepared by the co-precipitation of Fe-Cu-Al precursors, followed by potassium impregnation. The FT reactions using balanced feed gas with various CO/CO2 ratios were performed in a fixed bed reactor. The COx conversion to hydrocarbons decreased with the CO/CO2 ratio in feed gas. X-ray photoelectron spectroscopy and X-ray diffraction results showed that high CO/CO2 ratio favored the formation of iron carbides. Overall, low CO/CO2 ratio in feed gas was effective to inhibit the coke formation. |
