Regeneration of Used Oils by Red Mud and DESs (Reline)

Abstract To regeneration of oils which are used in cars engines to lubricate its moving parts, and to get rid of highly contaminants which must be separated to reuse the engine oils. In the column chromatography, the waste oil was treaded as mobile phase (eluent) with petroleum ether (40-60°C), whil...

Summary:Abstract To regeneration of oils which are used in cars engines to lubricate its moving parts, and to get rid of highly contaminants which must be separated to reuse the engine oils. In the column chromatography, the waste oil was treaded as mobile phase (eluent) with petroleum ether (40-60°C), while the red mud (alhuor) is a stationary phase for adsorbed the impurities. The effect of the new method using deepeutectic solvent (DESs Reline) as a kind of ionic liquids to help extract impurities by adsorption (choline chloride and urea). Moreover, some thermal and physicochemical properties like density, thermal and electrical conductivity, ash percentages, viscosity, specific gravity and pH values were determined. Values were determ.using TGA for blank oil for comparison and differential scanning calorimetric analyses (DSC).
