 This study examined the effectiveness of a new cocktail extraction agent, CEA, composed of solvent and a new surfactant material, SM, for recovering fuel from waste oil sludge, WOS. The results demonstrated that the CEA improved the extraction efficiency by dispersing the solvent into the WOS and improving the mixing and mass transfer rates. The best CEA, MEK and DAOFAX, provided the highest fuel recovery rate of 97%, achieved after 20 minutes of extraction at a temperature of 60 degrees Celsius and a CEA, WOS ratio of 4 to 1. The produced fuel was then analysed and found to be suitable for further processing. This article was authored by J.C. Myhamidi, Sadej Jaffa, Nisrin SLE, and others.
