Abstract: A feasible way to utilize the low value soft wax is to convert it into synthetic hydrocaxbon lube oil by thermal cracking/polymerization route.The first commercial plant for this purpose has been in normal operation since 1970.It has been proved to be economically sound.The antioxidant response of the product polymer oil can be distinctly improved by hydro-refining.It has been found that the vacuum gas oil from highly waxy crude with or without furfural refining can be used as cracking stock.If high viscosity index polymer oil is desired,it is better to use slack wax as the cracking stock.

摘要： 一、序言目前我国生产的原油大部分是高蜡的.大庆原油的含蜡量为25%.从这类高含蜡的原油采用常规润滑油加工方法生产低凝、高粘度的润滑油产品是比较困难的.因此需要探索一条新的途径.采取裂解—聚合方法生产合成润滑油在文献中很早就有记载.
