| Abstract: | The refining of vehicle waste lubricant oil using the furfural as the main solvent and sodium dodecyl benzene sulfonate as the cosolvent were studied.The influence of mixed solvent ratio,extraction temperature and other factors on the yield and quality of recovery refined oil are also investigated.It turns out that when the temperature is 80 ℃,the catalyst oil ratio is 1.5,the additive precentage of sodium dodecyl benzene sulfonate is 0.025%,the properties of refined oil with high yield(91.26%)islistedas follows: the viscosity index is 116.83,the refractometer index on 25 ℃ is 1.441,the chromatic is 2.0,the condensation point-19 ℃,w(carbon residue) is 0.496%.The refined lubricated oil after adding some additive can meet the requirements of lubricant oil,and can be reused. |
