SHAKIRULLAH, MOHAMMAD; AHMAD, IMTIAZ; AHMAD, WAQAS y ISHAQ, MOHAMMAD. DESULPHURIZATION STUDY OF PETROLEUM PRODUCTS THROUGH EXTRACTION WITH AQUEOUS IONIC LIQUIDS. J. Chil. Chem. Soc. [online]. 2010, vol.55, n.2, pp.179-183. ISSN 0717-9707. http://dx.doi.org/10.4067/S0717-97072010000200007.
Desulphurization of jet fuel, diesel oil, heavy residue and commercial furnace oil is carried out through extraction with aqueous solutions of sodium chloride, barium chloride, sodium hydroxide, mercury chloride, arsenic trioxide, potassium iodide, lead acetate, calcium hydroxide, zinc chloride, aluminum chloride, hydrochloric acid and sulphuric acid. Among the solutions used, HgCl2 and Ca(OH)2 were found to be the most efficient for the removal of sulphur compounds from the fractions understudy at 40 °C temperature and 30 min of shaking time. The total sulphur depletion of 60 % and 58 % has been achieved in case of jet fuel oil, 71 % and 62 % in case of diesel oil, 68 % and 67 % in case of heavy residue and 67 % and 69 %in case of commercial furnace oil with 10% HgCl2 and 5% Ca(OH)2 aqueous solutions, respectively.
