Recovery Of Used Lubricating Oil by Glacial Acetic Acid with Two Different Activated Carbons

Recovery of used lubricating oil (ULO) generally comprises cleaning, drying, and adsorption in order to eliminate water, sludge, and impurities. As the ULO is one of the hazardous wastes generated in various industrial and automotive industries, it should not be used or disposed of in ways that are...
