Fractionation produced five categories: naphtha, kerosene, light gas oil (LGO), heavy gas oil (HGO), and fuel oil. The research focused on distillation cuts of LGO (241–300°C) and HGO (301–360°C), which contained organic sulfur compounds, contributing to environmental pollution and health hazards during combustion. Oxidative desulfurization (ODS) using hydrogen peroxide and acetic acid at 75°C for 12 hours significantly reduced sulfur content. LGO sulfur content decreased from 0.72% to 0.11% wt in SA and from 2.02% to 0.50% wt in TA, achieving desulfurization efficiencies of 84.72% and 74.25%, respectively. In HGO, sulfur content dropped from 3.67% to 1.78% wt in Kh, with 51.49% efficiency. Gas oil recovery after oxidation ranged from 92.71% to 96.28%. Solvent extraction with acetonitrile, methanol, and acetic acid further enhanced desulfurization, with pre-oxidation extraction achieving 19.42% efficiency in LGO, increasing to 86% post-oxidation. Gas chromatography with a flame photometric detector (PFPD) assessed sulfur removal, highlighting the combined effects of oxidation and extraction on sulfur compound reduction. This approach demonstrated the efficiency of ODS in mitigating sulfur-related impacts.</div></div>","PeriodicalId":17081,"journal":{"name":"Journal of Sulfur Chemistry","volume":"46 2","pages":"Pages 324-344"},"PeriodicalIF":2.1,"publicationDate":"2025-03-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143576750","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
