Recent Advances in the Science and Technology of Desulfurization of Diesel Fuel Using Ionic Liquids

Sulfur-containing compounds in transportation fuels are converted by combustion to SOx, which is a major source of acid rain and air pollution [1]. For environmental protection pur‐ poses, many countries have mandated a reduction in fuels sulfur level down to 10 ppm by 2009 [2,3], and with more and more stringent regulatory constraints, it is a trend to achieve little-to-no sulfur fuels in the next several years.
