Abstract
내연기관에서 채취한 폐유를 황산백토 처리하여 얻어진 재생유는 원래 들어 있던 첨가제. 특히 산화방지제와는 상관없이 산화안정성이 좋아졌다. 이러한 성질의 개선은 방향족화합물이 거의 25%나 증가하는 사실로 미루어 수산화성물질의 생성에 기인하는 것으로 고찰된다.

The regenerated lubricating oils for an internal combustion engine, obtained from the sulfuric acid and clay treatment, showed an improved thermal oxidation stability regardless of additives, especially anti-oxidant, originally presented in the oils. It is believed that such improvement is due to the formation of anti-oxidant materials, which is observed by the in crease of 25 % of aromatic compounds.
