Used oil residue applies to a non-volatile residual stream generated as a by-product of re-refining and re-processing operations. Refined used oil and clay-treated used oil are base oils with commercial and industrial applications, and the end-products of the re-refining process.


oil was mixed with the activated bentonite in a variable percent-age ration of clay/extracted oil, extraction temperature, and mix-ing time at a constant speed of ~500 rpm. The next stage involved separating the recovered base oil adsorbent clay using a filter paper type 542 Whatman. The final stage involved an analysis of the pro-duced base oil.

4.3. Viscosity. Kinetic viscosity of used engine oil can be increased due to oxidation or contamination, while it may also be decreased due to dilution with light fuels (diesel or petrol) [].Viscosity of fresh lube oil is 90 cP, used engine oil 120 cP, which shows presence of contaminations in used engine oil, where the viscosity values of refined engine oils by …


Purification process of the used oil: The used engine oil was purified using the various clay samples. Beginning with the activated clay, it was ground and mixed with the used engine oil that had been pre-heated for 5 min. The mixture was then thoroughly blended together with the aid of a stirrer. The mixture was kept 24 h to allow for
