- 中文摘要: Used lubricating oil from vehicles was treated with various types of chemicals to be regenerated. It was found that used lubricating oil could be reclaimed with sulphuric acid, sodium hydroxide, sodium phosphate, ammonium sulphate and rosin. Viscosity and pour point of the reclaimed lubricating oil were improved with the additive methyl metha crylate. The reclaimed lubricating oil was characterized by four-ball machine and it was found that wear scar diameter (WSD) has greatly been decreased with the reclamation. The results of atomic absorption spectrophotometer also show that wear metals have also been decreased to an appreciable amount in the reclaimed lubricating oil.
