PHOTOOXIDATIVE-EXTRACTIVE DEEP DESULFURIZATION OF DIESEL FUEL USING Cu-Fe/Ti02 AND EUTECTIC-BASED IONIC LIQUIDS

Due to the dramatic environmental impact of sulfur oxides contained in engines
emissions, sulfur content specification in fuels are becoming more and more stringent
worldwide. Hydrodesulfurization (HDS) is the conventional process to reduce sulfur
levels if the fuels. However, HDS requires high temperature and high pressure in
order to eliminate the sulfur species. Refractory sulfur species such as
dibenzothiophene and its alkyl derivatives are less reactive to this process. Due to this
reason, alternative sulfur removal methods are being explored.
