从滤土中回收润滑油的新方法及其在碱性条件下的脱附机理

A New Method to Recover Lubricant Oil from Activated Alumina and the Destorption Mechanism on the Condition of Alkalinity

介绍了一种脱附润滑油的新方法———生石灰法,即将滤土加入沸腾的石灰水中加热、搅拌即可使润滑油脱附。该法较烧碱法更廉价、更有效。并提出了碱性条件下润滑油从活性白土中脱附的机理,并解释了两种脱附方法,应用了配位化学模型。

The paper introduces a new method of recovering lubricant oil from activated alumina.The qiuck line method refers to putting absorbed activated alumina into boiling water that contains quick line,then keeping on heating and stirring it simultaneously and finally desorbing lubricant oil from it.Compared with the caustic soda method,the quick line method is cheaper and more effective.The author advances the mechanism of desorption of lubricant oil from activated alumina on the condition of alkalinity and explains the two methods of desorption and applies the coordination chemistry mode to the desorption mechanism \;
