Abstract

In this work two single (ethanol and 1-butanol) and one composite (1-butanol-ethanol) solvents were used for refining Used Lubricating Engine Oil (ULEO) at temperatures 35ºC, 45ºC and 50ºC. The solvents performances were investigated at Solvent Oil Ratio (SOR) 1:1 to 7:1 using percentage oil yield as performance metric. The study revealed that 1-butanol produced the best performance for regenerating ULEO. The results of this study demonstrated the potential of 1-butanol-ethanol for regenerating ULEO.
