本文合成了一系列聚乙烯醇担载离子液体薄膜,并进行了FT-IR,SEM以及DSC表征.通过对模拟汽油脱硫性能的初步研究发现,这一类薄膜对于较低硫含量的体系具有较好的脱硫性能.
Recently, the exploration of using ionic liquid in gasoline desulfurization has attracted extensive attentions. Directly using ionic liquid as an extractant for liquid/liquid extraction or as solvent for the oxidative desulfurization of model oil, commercial diesel and light oils, etc, were reported and perfect results were obtained. In order to make the operation more practically usable, herein, we present our new attempt to prepare a Polyvinyl alcohol (PVA) supported ionic liquid membrane and its possibility to be used in gasoline desulfurization.
