摘要: 采用杂多酸/丙酮体系进行了润滑油基础油的脱氮研究,考察了脱氮工艺条件对脱氮率及脱氮油理化性质的影响。结果表明,杂多酸/丙酮体系可以选择性地脱除基础油中的含氮化合物,脱氮前后基础油中疏含量变化不大,脱氮油的氧化安定性得到显著提高,且脱氮过程不影响油品的其它理化性质。杂多酸脱氮过程的开发为提高润滑油基础油的质量提供了一种新的途径。

Abstract: Employing heteropoly acid/acetone system as chemical extractant, a novel process was developed to selectively remove nitrogen-containing compounds from lubricating oil base stocks. The results showed that the process can effectively reduce the content of nitrogen-containing compounds and thus greatly increase the antioxidative stability of the lubricating oil base stocks, without significantly lowering sulfur content and affecting other physical and chemical properties of the refined base stocks. This work may provide an alternative way for denitrification of lubricating oil base stocks.
