Title: Conversion of hazardous materials using supercritical water oxidation

Abstract

This patent describes a method of treating hazardous materials containing organic contaminants without adding an oxidant material to the hazardous material, wherein the chemical elements comprising the organic contaminants are caused to rearrange into molecules of chemical compounds which are benign and/or easily treatable, and wherein the chemical elements comprising the organic contaminants contain an amount of oxygen effective for the rearrangement to take place. It comprises: mixing the hazardous materials with water to form a mixture; increasing the temperature of the mixture to a value above about 500[degrees]C, and increasing the pressure to a value above about 4500 psig; holding the mixture at the temperature and pressure for a period of time sufficient for the rearrangement to take place; and cooling the mixture comprising the benign and/or easily treatable compounds.
