| Abstract: |
| Filtration and separation technologies are an important technology in the treatment of waste oil, and there are many filtration and separation methods for waste oil in the market. According to the application characteristics of filtration and separation technologies for waste oil, the technologies include the process of the treatment for impurities and moisture removal, adsorption separation technology and membrane separation technology of waste lubrication oil, removing the residual solid catalyst after refining oil, filtration, separation and hydrocyclone of catalytic cracking oil, and extracting recycled materials such as polycyclic aromatic hydrocarbone and so on by gradient elution in coal tar. From the perspective of filtration and separation technologies in the treatment of waste lubricating oil, catalytic cracking oil slurry and coal tar, this paper reviews the present application situation of filtration and separation technologies, and proposes that future research should focus on filtration and separation technologies with non pollution and with efficiency in the process of waste oil treatment. |
