Photo Oxidative Extractive Desulfurization of Model Oil Using Fe/TiO_2 Photocatalyst and Eutectic Based Ionic Liquid: Effect of Metal Loading

摘要

Titanium dioxide (TiO_2) photocatalyts doped with iron metal at different metal loadings were successfully prepared and characterized. The doped photocatalysts were characterized using Diffuse Reflectance Spectroscopy (DR-Uv-Vis), X-ray Diffraction (XRD) and Field Emission Scanning Electron Microscope (FESEM). Photooxidative extractive desulfurization of model oil containing dibenzothiophene as the sulfur compound (100 ppm) was investigated using the prepared photocatalyst. The photocatalyst with 0.20 wt% Fe metal loading showed the best sulfur removal at 61.13%.
