ABSTRACT:
A process for eliminating by destruction polychlorinated bi-phenyls from hydrocarbonaceous oil contaminated therewith is disclosed. The oil is admixed with liquid sodium in an atmosphere of argon gas and allowed by refluxing, mixing, agitation, and hydrogenation circulation to react therewith. The polychlorinated bi-phenyls are eliminated, the reaction products are filtered and the uncontaminated treated oil is rendered susceptible to re-use.
