In contrast, it is necessary to find an innovative way to remove sulfur and carcinogenic aromatic compounds because clean, low-sulfur diesel is commonly used in all countries of the world at the present time. Therefore, in this work, we have studied the effect of the microwave radiation power and the irradiation time with the use of more than one type of organic solvent; methanol, acetonitrile and ethyl acetoacetate; as an extractant and solvent to feed ratio impact on the removal of sulfur and aromatic compounds of a real diesel fuel feed which has 450\u00a0ppm sulfur content and 16\u00a0wt% aromatic Content. The results showed that the best solvent used during this work was ethyl acetoacetate. According to the results, high sulfur removal (\u2248\u200992%) was accomplished with microwave-assisted extractive desulfurization technique under the following ideal conditions: the irradiation time is 7\u00a0min, the solvent feed ratio is 3:1 and the microwave intensity is 180\u00a0W. To reveal the mechanism of microwave-assisted extractive desulfurization via different organic solvents, a theoretical study including structural examination and interaction energy analysis on the interaction between dibenzothiophene (DBT) or dimethyl dibenzothiophene (DMDBT) and the different organic solvents was also conducted.<\/jats:p>","DOI":"10.1186\/s13065-024-01292-2","type":"journal-article","created":{"date-parts":[[2024,10,14]],"date-time":"2024-10-14T18:02:12Z","timestamp":1728928932000},"update-policy":"http:\/\/dx.doi.org\/10.1007\/springer_crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["The role of microwave radiation in extractive desulfurization of real diesel fuel for green environment: an experimental and computational investigation"],"prefix":"10.1186","volume":"18","author":[{"given":"Hamida Y.","family":"Mostafa","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ghada E.","family":"Khedr","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ard Elshifa M.
