介绍了一种润滑油基础油高效固体脱氮工艺。该工艺是在白土精制过程中加入少量WLDN固体脱氮剂 ,反应完毕后过滤 ,则碱性氮化物与白土一起被脱除。该工艺简单 ,投资少 ,成本低 ,脱氮效果好 ,对原料适应性强 ,对环境无污染 ,是润滑油生产厂提高产品质量的有效方法。该脱氮工艺适宜的操作条件为 :脱氮剂用量 1%,白土用量 1%,反应温度 10 0～ 130℃ ,反应时间 2 0～ 30min。
A high efficiency solid nitrogen removal process of lubricating base oil is introduced. The process is in the clay refining process by adding a small amount of WLDN solid nitrogen removal agent, the reaction is filtered, the basic nitride and clay are removed together. The process is simple, low investment, low cost, good effect of denitrification, strong adaptability to raw materials and no pollution to the environment, and is an effective method for the lubricant production plant to improve product quality. The optimum operating conditions for the denitrification process are as follows: the amount of denitrifying agent is 1%, the amount of white clay is 1%, the reaction temperature is 10 ~ 130 ℃, and the reaction time is 20 ~ 30min.
