China is the worlds second largest oil consuming countries, consumption is also growing. Of waste lubricating oil recovery rate less than the oil of the total 20% and developed countries about 40% -50% of the direct emissions of waste lubricating oil environment, the impact on the environment. In the worlds energy is increasingly tense, and the grim situation of environmental pollution, waste oil recycling and regeneration issues that need to be urgently addressed. To investigate a low cost, and the results are satisfactory regeneration process of waste lubricating oil, waste lubricating oil in our use of the SAE 5W-40 has carried out a series of experiments. Used: Pretreatment - separation - the refining process can achieve the desired requirements. With the method of settlement filtering in the preprocessing stage to remove the moisture and mechanical impurities in the separation stage by vacuum distillation (-0.09MPa) to extract the 220-280 ° C oil fractions in the refining stage of selection of the oil quality of 10% clay refining out of the base oil fractions, the results show that you can get better purity of the lubrica
