IONIC LIQUID EXTRACTION CLEANING OF PETROLEUM FRACTIONS

The extraction purification process is currently being intensively studied and has a great future as an alternative method of petroleum fractions. point that the development technology rise in consumption fuels oils calls for tightening requirements to their quality characteristics. At same time, special attention paid content aromatic hydrocarbons, sulfur-containing resinous compounds composition. present review considers results studies extractive various oil fractions using both traditional "green" solvents - ionic liquids extractant providing effectiveness ion-liquid purification. article also describes on combining with oxidative method. carried out at Institute Petrochemical Processes National Academy Sciences Azerbaijan distillates purposes, particular, transformer distillate, catalytic cracking reforming gasoline, AMG-10 hydraulic fluid, Naftalan oil, diesel fuel, well different viscosity values, are shown article. Also, possibility getting products when used selective solvent (morpholformate, anilinformate, N-methylpyrrolidone acetate, etc.) differing cationic-anionic combination substantiated.
