Organic sulfides in fuels have become one of the main sources serious pollution. The desulfurization has a frontier scientific topic demanding prompt solutions. Research shows that emergence ionic liquid analogues—deep eutectic solvents (DESs)—has provided new opportunity for deep extraction because their cheap and easily obtained raw materials, higher efficiencies, simple environmentally friendly synthesis process. In this study, some DESs were designed synthesized. Choline chloride (ChCl),...

The combustion of fuel oil releases sulfur compounds, which react to form oxides that are harmful the environment and pose a threat human health. To mitigate these negative effects, it is crucial pretreat through desulfurization processes. One promising approach involves use deep eutectic solvents (DESs), carbon nanotubes (CNTs), their composites (DESs/CNTs) effectively reduce content in oil.However, conventional methods DES-based extraction CNT-based adsorption suffer from low rates....
