摘　　要：为了防止环境污染，我国很多城市正在或打算采用ＬＰＧ作为车用燃料。但是，ＬＰＧ 中烯烃的存在将影响使用质量，烯烃燃烧结炭引起汽缸磨损、管路堵塞，丁二烯会损伤橡胶件等等，因此希望采用不含有烯烃的ＬＰＧ。这种ＬＰＧ产自油气田，但油气田生产的ＬＰＧ不足。因此，人们把眼光投向炼油厂甚至石油化工厂，希望从其获得无（ 低）烯烃ＬＰＧ。着重分析了炼油厂ＬＰＧ源，初步讨论了ＬＰＧ 脱烯方法、提出了采购无（低） 烯烃ＬＰＧ 原料的路子和今后要做的工作。In order to prevent environmental pollution,LPG is being used or is planned to be used as vehicle fuel in many cities in China.But the existence of alkene in LPG has an effect on the quality in use.The carbon formed after alkene was burned away causes the cylinder to be worn and the tube to be blocked,and the butadiene will damnify the rubber parts,therefore,the LPG that does not contain alkene is hoped to be used.But the LPG produced in oil and gas fields is insufficient,thus people throw a look to refinery even to petrochemical plant and hope to obtain the LPG without alkene (or with low alkene content).In this paper,the LPG resources of refinery are emphatically analyzed,the dealkenizing method is preliminarily discussed and the way to purchase raw LPG without alkene (or with low alkene content)and the works to be done in future are proposed.
