Abstract
A method relates to treating a halogenated organic waste to produce halogen gas and carbon oxide gas streams. The method includes directing a halogenated organic waste, having a halogen-to-hydrogen atomic ratio of less than about one, into a molten metal bath. The molten metal bath is inert to the halogen and has a free energy of oxidation greater than that of the formation of carbon monoxide from atomic carbon. The halogenated organic feed is converted into halogen gas and atomic carbon, whereby the halogen gas is released from the molten metal bath. An oxidant is directed into the molten metal bath, whereby the atomic carbon is oxidized to form a carbon oxide gas, which is released from the molten metal bath.
