摘要：
In order to explore the high value-added utilization of flyash adsorption in regenerating waste lubricating oil, the main factors related to the flyash adsorption was investigated by the single-factor tests, and then the optimum process conditions for flyash adsorption was obtained by means of the orthogonal experiments, and in terms of several indexes, such as kinematic viscosity (40 °C), acid number, mechanical impurity and moisture, the combined process of flyash adsorption/solvent extraction was discussed and finally compared with previous studies. The experimental results prove that flyash has a good effect in adsorbing waste lubricating oil, and the solvent extraction-flyash adsorption process has a better effect in the regeneration of waste lubricating oil than the flyash adsorption-solvent extraction process.
