This investigation was carried out with the purpose of reducing the sulphur content in diesel from the topping plant and avoiding air pollution, due to the presence of SO_x in the emissions, at the same time reduced the corrosion rate in the equipment, machinery or mechanical components of the industry. An oxidative desulphurization (ODS) process was carried out with ionic liquid (1-butyl-3-methyl imidazolium hydrogen sulfate [BMIM][HSO₄]) that serves as a solvent and catalyst. H₂O₂ (30 % wt) was used as an oxidizing agent, because it is benign to the environment. A maximum of 43.14% removal was obtained at a volumetric ratio V_IL/V_diesel (1:1), molar ratio H₂O₂/S (5) and reaction time (2 hours). In addition, the IL was evaluated after subjecting it to a regeneration process, being able to recycle it only once until it is saturated again; also the physical-chemical properties of diesel were studied before and after of exposed it to the ODS process.

进行此项调查的目的是为了减少来自顶部工厂的柴油中的硫含量，避免由于排放物中存在 SO _x而造成的空气污染，同时降低设备、机械或机械的腐蚀速度。行业的组成部分。使用离子液体（1-丁基-3-甲基咪唑硫酸氢盐[BMIM][HSO ₄ ]）作为溶剂和催化剂进行氧化脱硫（ODS）工艺。H ₂ O ₂ (30 % wt) 被用作氧化剂，因为它对环境无害。_{在体积比 V IL} /V_柴油(1:1)、摩尔比 H下，最大去除率为 43.14%₂ O ₂ /S (5) 和反应时间（2 小时）。此外，IL 在对其进行再生过程后进行了评估，只能将其回收一次，直到再次饱和；还研究了柴油在 ODS 处理前后的物理化学性质。
