Abstract

Used lubricating ol is regenerated by (a) extracting with a liq. 3-6C alkane, separating the extract from the raffinate and removing the extractant from the extract, (b) distilling the extract to produce a distillate and a residue; (c) hydrogenating the distillate; and (d) treating the residue from (b) with an adsorbent. Since only the distillate is hydrogenated, the hydrogenation catalyst has a longer working life.
