深共融溶剂在燃油脱除有机硫化物中的应用
Application of deep eutectic solvents in the removal of organic sulfur compounds from fuel
摘要
Abstract
The extractive desulfurization of deep eutectic solvents (DESs) has provided a new green method for the deep desulfurization of fuel due to its simple operation, mild conditions, low cost and high desulfurization efficiency. This article summarizes the progress in the past five years on applying DESs in the removal of organic sulfur compounds from fuel, including direct extractive desulfurization and oxidative-extractive desulfurization. Firstly, the desulfurization results of different DESs are summarized.For example, the extraction efficiency of dibenzothiophene is 100% after three extraction stages by tetrabutyl ammonium bromide/polyethylene glycol; the removal efficiency of dibenzothiophene can reach100% for oxidative desulfurization with choline chloride/acetic acid as an extractant. The desulfurization of DESs can meet the requirement of ultra-low sulfur. The factors influencing the desulfurization efficiencies of DESs, such as the structures of DESs, the temperature and time of desulfurization, ratio of DESs to oil, types and concentrations of sulfides, and oxidants are also analyzed. Then, the recovery methods of DESs are summarized, and the problems in the recovery process are pointed out. The mechanisms of desulfurization are also discussed. Finally, the problems of DESs desulfurization are pointed out and the prospect of DESs in the desulfurization of fuels is reviewed.关键词
