Recently, deep desulfurization of gasoline and diesel oil has attracted much attention, due to the increasing demand of lower S-content diesel oil and gasoline, because sulfur-containing compounds is a source of SOx. Current hydrodesulfurization (HDS) process, however, has a limitation in removing S-compounds such as DBT and 4,6-Dimethyl-dibenzothiophene. In this regard, extraction of S-compounds from oil by ionic liquids (ILs) could be a promising alternative to conventional HDS. Sulfur-containing compounds which are hard to remove by HDS have been successfully removed under mild condition using various imidazolium-based ionic liquids. |
