Nowadays, desulfurization of liquid fuels is inevitable because of strict environmental and industrial regulations on liquid fuels specifications. Hydrodesulfurization (HDS) technology has been used widely to produce fuels with ultralow sulfur content (S ≤ 10 ppm). However, this method is not effective enough for removing refractory sulfur …
Li et al. reported a kind of ammonium-based deep eutectic solvents on extractive desulfurization and the sulfur content in fuels can be reduced to less than 8.5 ppm after five cycle [37]. Recently, the group developed 'Metal Ions' DESs and the extractive efficiency could be promoted effectively [38].
