摘要：
Regeneration of used lubricating oils by supercritical fluid extraction were investigated. The broken-down additives and impurities were removed by the high selectivity of supercritical fluid, and high-quality tube oil was obtained. Corrosion and waste-disposal problems produced by older acid-clay process have been lessened.
