聚异丁烯胺合成工艺及高性能汽油清净剂技术

Synthesis Process for Polyisobutene Amine and Technology for High Performance Gasoline Detergent

汽油清净剂以聚异丁烯胺为主剂复配而成,加入到汽油中抑制、清除沉积在发动机燃油进气系统中的沉积物,改善汽油燃烧系统状况,降低汽车尾气排放中的一氧化碳、碳氢化合物等有害物质,提高燃油的经济性。聚异丁烯胺合成工艺及汽油清净剂复配技术是中国石油吉林石化公司自主研究开发的专有技术。介绍了聚异丁烯胺合成工艺、清净剂复配技术及作用机理。产品具有良好的进气系统清净性,燃烧室沉积物几乎不增加,质量达到国际同类产品水平,填补了国内汽油清净剂主剂生产空白,解决了全部依靠进口的局面。

Gasoline detergent is mainly compounded with polyisobutene amine as the main agent.It is added to gasoline to inhibit and remove sediments that deposited in engine fuel air intake system,so as to improve gasoline combustion system,reduce emissions of carbon monoxide,hydrocarbons and other harmful substances in the tail gas of vehicles,and improve fuel economy.The synthesis process of polyisobutene amine and the compound technology for gasoline detergent are the proprietary technology researched and developed independently by CNPC Jilin Petrochemical Company.In this paper,the synthesis process of polyisobutene amine,and the compound technology and acting mechanisms of gasoline detergent are introduced.The product has good detergency for air intake system and eliminates the deposits in combustion chamber.The quality has reached the international level of similar products,which fills the gaps of production of base agent for gasoline detergents in China,and it is not necessary to import all the main agents.
