| 摘要 |
The present invention relates to a process for the purification of contaminated oils, mainly hydrocarbon oils or polyether oils wherein the contaminated oil is treated by an base solution in the presence of an adsorbent and then water is removed by distillation without the separation of the liquid-phases and the impurities adsorbed on adsorbent are separated preferably by filtration. The oils purified by the process become applicable for energy-supply in commercial furnaces or become utilizable in other types of technologies. |
