Title: Process for removing polychlorinated and polybrominated biphenyls from oils

Abstract

The invention is a relatively simple and inexpensive process for detoxifying oils contaminated with PCBs and/or PBBs. The process is especially suitable for processing lubricating oils containing such contaminants. In one aspect of the invention, the contaminated lubricating oil is contacted with a particulate reagent comprising adsorbent particles carrying a dispersion of metallic sodium. The solid sodium reagent converts the PCB and/or PBB contaminants to environmentally acceptable products and also converts various sodium-reactive additives normally present in lubricating oil to reaction products. The adsorbent reagent retains most of the products and is easily separated from the detoxified oil. The detoxified oil may be fortified with various additives functionally equivalent to those removed during detoxification.
