摘　　要：为了降低生产成本 ,提高产品质量 ,新的润滑油基础油脱蜡技术———异构脱蜡技术得到开发并不断改进。该技术采用一种新型催化剂使蜡异构 ,从而获得较溶剂脱蜡和催化脱蜡都高的粘度指数 ,已被越来越多的润滑油基础油生产商所采用 ,代表了润滑油基础油脱蜡技术的发展趋势。讨论了该技术的催化反应化学、催化剂及工艺特点 。Faced with the pressure to reduce process cost and improve base oil quality,the isodewaxing technology as a new lubricant base oil dewaxing technology,has been developed and improved continuously.This process is based on a new catalyst which can make wax isomerize,and provide higher Ⅵ base oils than solvent dewaxing or other catalytic dewaxing processes.This process has been adopted by more and more manufacturers,becoming the development trend of lube base oil dewaxing technology.The catalytic chemistry,the catalysts and the technique characteristics of this process are discussed,meanwhile the start up and the running of the plants which use this process,both in China and abroad,are introduced.
