Synthesize of NiMo/F-Al2O3 Nanocatalyst using Fluorine-Modified Impregnation Method for Desulfurization of Hydrocarbon Fuels

In this research, NiMo/F-Al2O3 nanocatalysts were synthesized using impregnation method and modified with different fluorine contents. The synthesized nanocatalysts were examined toward hydrodesulphurization of thiophene. The physicochemical properties of nanocatalysts were assessed by XRD, FESEM, BET and FTIR analyses. Structural and surface properties of nanocatalyst with optimum fluorine contents (1 wt.%) were more favorable than of fluorine-free nanocatalyst. Results show that the surface area of the samples was increased with addition of fluorine, while the catalyst particle size was reduced. Activity of nanocatalysts in the conversion of thiophene showed that the amount of sulphur in final solution was reduced down to 100 ppm. The increasing in activity could be addressed by increasing surface area and excellent structural properties of these nanocatalysts.
