摘要： A used lubricating oil comprising lube oil additives, including zinc dithiophosphate is subjected to reclaiming. Zinc dithiophosphate is thermally decomposed at a temperature of 400.degree. F. (204.degree. C.) to 1000.degree. F. (538.degree. C.) for a residence time of 10 to 120 minutes. The resulting oil is subjected to vacuum distillation. A zinc-free (i.e. ash free by ASTM D-482) distillate oil is useful as marine diesel fuel. About 5 to 25 vol % is recovered as a metal containing bottoms product, useful as asphalt extender. The process is carried out in the absence of chemical demetallizing.

摘要： A used lubricating oil comprising lube oil additives, including zinc dithiophosphate is reconstituted. Zinc dithiophosphate is thermally decomposed at a temperature of 400.degree. F. (204.degree. C.) to 1000.degree. F. (538.degree. C.) for a residence time of 10 to 120 minutes. The resulting oil is subjected to vacuum distillation. A zinc-free (i.e. ash free by ASTM D-482) oil is stabilized by catalytic hydrogenation or clay treating to produce a lubricating oil blending stock. About 5 to 25 vol % is recovered as a metal containing bottoms product, useful as asphalt extender. The process is carried out in the absence of chemical demetallizing.
摘要翻译： 包含润滑油添加剂（包括二硫代磷酸锌）的二手润滑油被重新配制。 二硫代磷酸锌在400°F（204℃）至1000°F（538℃）下热分解停留时间为10至120分钟。 将所得油进行真空蒸馏。 通过催化氢化或粘土处理使无锌（即通过ASTM D-482无灰分）的油稳定，以产生润滑油共混料。 约5至25体积％的回收作为含有底物的金属产物，可用作沥青增量剂。 该过程在没有化学脱金属的情况下进行。
