摘　　要：倾点作为润滑油基础油低温流动性一项重要指标,与脱蜡技术密切相关。根据含蜡原料生产基础油过程中脱蜡技术的不同,介绍了3种脱蜡技术:溶剂脱蜡、催化脱蜡和异构脱蜡,并着重阐述了目前国内外主流脱蜡技术——异构脱蜡技术,为煤间接液化技术加氢重油生产低倾点、高收率和高品质合成润滑油基础油提供理论指导。Pour point is an important indicator of low temperature fluidity of lubricating base oils, which is closely related to dewaxing technology. According to the different dewaxing technologies in the production of base oils from waxy raw materials, three kinds of dewaxing technologies were introduced,including solvent dewaxing, catalytic dewaxing, and isomerization dewaxing.The isomerization dewaxing technology as a current mainstream domestic and international dewaxing technology was elaborated. The paper can provide theoretical guidance for the production of low pour point, high yield and high quality synthetic lubricating base oils for the indirect liquefaction technology of hydrogenation tail oil.
