| Abstract: | The refining of industrial waste lubricating oil was investigated with N-methyl-2-pyrrolidone(NMP) and Duo-solvent(ethanolamine and NMP) as solvents,respectively.The preferred refining process is duo-solvent refining under 70 ℃ with 5% ethanolamine,under these conditions the total oil yield was 89.85%.The physical properties of recycled oil is listed as follows: viscosity(40 ℃) 30.89 mm2·s-1,viscosity(100 ℃) 5.6 mm2·s-1,viscosity index 120.4,refractive index 1.450,Color 2.0,freezing point-28.8 ℃,flash point 219.6 ℃ and sulfur content 0.057%. |
