Abstract: The regeneration technologies of waste lubricating oil in recent years were reviewed. The regeneration of waste lubricating oil was tested in a short-path distillation unit with activated white clay as adsorbent. The quality of regenerated oil met the requirements of new oil standards. The technology used in the test had high recovery efficiency and short operation period，and caused no secondary pollution. It was friendly to the environment and had great social and economic benefits.
