Advances in desulfurization of gasoline by pervaporation technology

With the enforcement of increasingly stringent environmental laws,strict regulations of the sulfur levels in gasoline have been mandated in most countries.Coupling with the inevitable trend of the production of ultra-low-sulfur or even sulfur-free gasoline,technologies for deep-desulfurization of gasoline have been turned be a key area of research.As a novel separation technology based on polymer membranes,the pervaporation process has its unique predominance when used in sulfur removal from gasoline.The principle,characteristics and the advances in desulfurization of gasoline by the pervaporation process are briefly introduced in this paper.
