Реферат: "CLAY CONTACTING PROCESS FOR REMOVING CONTAMINANTS FROM WASTE LUBRICATING OIL" ABSTRACT OF THE DISCLOSURE A process is provided for removing contaminants from waste lubricating oil. The previously untreated waste oil is contacted with decolorizing clay at a temperature in the range of about 650 - 725°F and the clay-oil mixture filtered to produce a filtrate product re-duced in contaminants. The clay contacting step may optionally be performed in a hydrogen atmosphere. The filtered product can be used for non-critical uses or further upgraded by conventional methods.
