Full-Scale Hydrotreatment of Polychlorinated Biphenyls in the Presence of Used Lubricating Oils

摘要

Approximately 850 000 L of used oil contaminated with polychlorinated biphenyls was processed through a full-scale re-refinery using a vacuum distillation/ hydrotreatmenttechnology. The catalytic reaction with hydrogen not only destroyed the PCBs but also generated useful petroleum products, including lubricating oil. Testing of the used oil feed as well as all intermediates, byproducts, and products allowed for the monitoring of the fate of the PCBs and demonstrated their destruction.
