PROCESS FOR REMOVING CONTAMINANTS FROM THERMALLY CRACKED WASTE OILS

摘要

A process is described for removing contaminants from thermally cracked waste oil, e.g. used motor oil. In the process the cracked waste oil is contacted with a solvent comprising methanol. The thermally cracked waste oil is then separated from the solvent whereby a substantial portion of the contaminants are removed into the solvent. Thereafter, the solvent is separated from the contaminants and recycled.
