【Abstract】 The experiment on extraction of lubricating oil by using mixed solvent was carried out both batchwise and continuously. The effect of mixed solvent composition (furfural to epichlorohydrin ratio), solvent to oil ratio, and operating temperatures on the yield and quality of the refined oil was studied. The results showed that the efficiency and selectivity of the extraction process concerned was improved by using this mixed solvent as compared with using furfural alone.更多还原
