摘要: |
应用分子蒸馏法再生废润滑油,以残炭、黏度、酸值作为表征再生油品性能的指标,考察了不同工艺条件下得到的再生油品的性能;实验结果表明: 随着温度升高,再生油品的残炭含量、黏度、酸值都呈现出整体上升的趋势,综合考虑应将分子蒸馏温度控制在180 ℃左右;随着压力升高,再生油品的残炭含量、黏度、酸值均呈现出下降的趋势,因此分子蒸馏压力应控制在50 Pa以下;当分子蒸馏温度为180 ℃,分子蒸馏压力为50 Pa时,得到再生油较之废润滑油原料,不仅外观上有明显变化,其残炭含量、酸值也大幅下降,再生效果显著。 |

Abstract: |
The regeneration of the waste lubricant oil is taken by molecular distillation with adjusted parameters.The performance of the regeneration oil is mainly decided by the determination of carbon residue,kinematic viscosity and acid number.Experimental results show that the value of carbon residue,kinematic viscosity and acid number all increase with the increasing temperature.For the comprehensive consideration,the temperature should be controlled at 180 ℃.It can also be found that the value shows a decline with the increasing pressure.As a conclusion,the pressure should be under 50 Pa.Compared with the waste lubricant oil,the regeneration oil which is obtained at 180 ℃,50 Pa,has ideal regeneration effect with ideal appearance,dereasing carbon residue and acid number. |
