Abstract
This invention comprises a wet oxidation process utilizing copper (II) oxide as the sole oxygen source. In particular the destruction and detoxification by oxidation of toxic materials such as cyanide, hydrocarbons, halogenated hydrocarbons, and dioxins contained in typically aqueous streams by using copper (II) oxide is contemplated. The preferred embodiment involves adding the copper (II) oxide to the feed stream containing the toxic materials and reacting the stream under elevated pressure and elevated temperature conditions to substantially oxidize the toxic materials to less toxic or innocuous compounds. The oxidation process can be accomplished in a vertical tube reactor system, wherein the necessary pressure for the wet oxidation is achieved by hydrostatic head pressure inherent in the system.
