Heavy metals are removed from waste lubricating oil by heating in the presence of an oxidation catalyst and a free radical initiator at temperatures in the range of about 150-200°C. Corrosion and oxidation inhibitors previously added to the oil are thereby oxidized to form a separable sludge which contains the bulk of heavy metal contamination. The process is of particular advantage in removing contaminating radioactive nuclides from lubricating oils used in nuclear generating facilities.
On élimine les métaux lourds des huiles lubrifiantes usées en les chauffant en présence d'un catalyseur d'oxydation et d'un initiateur de radicaux libres, à des températures comprises entre 150 et 200 .degré.C. Les inhibiteurs de corrosion et d'oxydation ajoutés à l'huile sont donc oxydés et forment une boue décantable contenant la plus grande partie de la contamination par les métaux lourds. Ce procédé est particulièrement intéressant pour éliminer les nucléides radioactifs contaminant les huiles lubrifiantes utilisées dans les centrales nucléaires.
