ABSTRACT:
A process is provided for removing contaminants from waste lubricating oil. The previously untreated waste oil is contacted with decolorizing clay and the mixture is heated to and retained for a period of time at a temperature in the range of about 650.degree.-725.degree. F., to render the mixture filterable. The product clay-oil mixture is cooled and filtered to produce an oil filtrate reduced in contaminants. The clay contacting step may optionally be performed in a hydrogen atmosphere. The oil product can be used for non-critical uses or further upgraded by conventional methods.
