| titleOfInvention | Method for cleaning liquid motor fuels of sulfur-containing compounds |
| abstract | The given method relates to a method for cleaning liquid motor fuels of sulfur-containing compounds, including of difficult-to-crack sulfur-containing compounds. The invention relates to a method for cleaning motor fuels (gasoline and diesel fractions, naphtha and gasoils produced from gas condensate and petroleum fractions), including extracting sulfur-containing compounds from a fuel into an ionic liquid, partially oxidizing the extracted sulfur-containing compounds under the influence of a catalyst in an alcohol alkaline solution or in an acidic aqueous solution, separating-out the hydrocarbon fraction, and regenerating the ionic liquid with the possibility of subsequently reusing same multiple times. The following are used as the ionic liquid: 1-hexyl pyridinium-bis(trifluoromethylsulfonyl)imide, 1-methyl-3-octylimidazolium tetrafluoroborate, 1-methyl-3-butylimidazolium tetrafluoroborate, 1-methyl-3-octylimidazolium triflate, 1-methyl-3-octylimidazolium hexafluorophosphate, 1-butylimidazolium hydrogen sulfate, and 1-methyl-3-butylimidazolium chloride. The catalyst is comprised of dissolved salts or oxides of transition metals selected from a group including molybdenum, vanadium, tungsten, manganese, and chromium. The partial oxidation is carried out in an alcohol alkaline solution or in an aqueous acid solution with the help of ozone, hydrogen peroxide, a superacid or a peroxide of organic acids. The technical result is an increase in the level of cleaning of motor fuels, wherein the extractant (IL) is capable of operating without a decrease in activity, relative to the sulfur-containing compounds, for up to 20-30 cycles, and for an additional 10-15 cycles following regeneration. |
