摘要: The object of the invention is a process for recycling used lubricating oils. After drying and gasoline removal, the oil is distilled and then treated with sodium or sodium hydride in a finely-divided state at elevated temperature. This is followed by a further distillation. Both distillations are at temperatures below 300.degree. C., the oil fractions of low volatility being respectively distilled in a molecular distillation apparatus at below 2 mbar.

摘要: In a method and apparatus for short-path, high-vacuum distillation from a liquid on plate-like evaporating surfaces from which distillable fractions evaporate and precipitate onto condensation surfaces a short distance away, the liquid is placed upon the evaporating surfaces at a temperature such that the energy required for its evaporation is taken, at least in part, from the still-unevaporated fraction of the liquid.
