| Popis: | In this work, we studied the desulfurization of Straight Run Gas Oil (SRGO) and diesel by selective oxidation and extraction of sulfur-containing compounds. The oxidation was carried out with a mixture of hydrogen peroxide at 30 wt% and acetic acid as catalyst. The extraction of the corresponding sulfones was performed with polar solvents (e.g., acetonitrile, methanol, 2-ethoxyethanol, and γ-butyrolactone). The SRGO has a sulfur content of 13,985 ppmw while diesel has 390 ppmw, the results showed sulfur removal to levels as low as 92 ppmw for diesel. From a consideration of the above results, a preliminary estimation of investment for a desulfuration process for hydrotreated diesel was done. |
