【 摘 要 】

In the following study two 20 wt% Co/Al2O3 catalysts were characterised.The difference in activity, selectivity and deactivation of these two catalysts, under typical low-temperature Fischer- Tröpsch (LTFT) conditions, were studied.The effect of co-feeding different liquids: alcohols, alkanes and aromatics into the system were also studied.Techniques used in this study included Brunauer, Emmett, Teller (BET) surface area analysis, Thermo-gravimetric analysis (TGA), Temperature-programmed-reduction (TPR), powder X-Ray Diffraction (XRD), TPR-UV-vis-NIR spectroscopy and Transmission Electron Microscopy (TEM).
