Abstract

A process for reducing the odor of an oil. The oil being treated is first distilled by a carrier vapor or carrier gas distillation to form a distilled oil. The distilled oil is then contacted with a polymeric adsorbent; whereby the odor of the oil is reduced. The polymeric adsorbent is regenerated. The polymeric adsorbent can be a cross-linked polymer with an internal surface area of from 900 to 1500 m2/gram.
