Preparation and Characterization of Fe/TiO2 Photocatalyst for Visible Light Deep Desulfurization

With the high concern related to sulfur content in diesel oil, Malaysia is working towards reducing the sulfur content in diesel from 300 ppm to 10 ppm. The primary objective of this work is to prepare and characterize Fe/TiO2 for visible light deep desulfurization. Titanium dioxide photocatalysis is the most effective photooxidative extractive sulfur removal. With the help of metal doping, the performance of desulfurization can be improved. Thus, loading of Fe onTiO2 is used in this experiment to investigate the performance of desulfurization under visible light. A wet impregnation method is used to prepare Fe/TiO2. Different loading of Fe (0.1 wt%, 0.2 wt%, 0.4 wt%, 0.6 wt%, 0.8 wt% and 1.0 wt %) with the calcination temperature of 350oC, 400oC and 450oC are investigate throughout the experiment. The calcination temperature, synergic effects of particle size and surface area play an important role in desulfurization.
