ABSTRACT:
A method of destroying halogenated compounds by a vapor phase chemical reaction using an alkali metal vapor, alkaline earth metal vapor, or a combination of the two, in a heated reactor to produce mineralized or solid products. The production of solid products, such as halide salts and particulate carbon, yields numerous advantages in the collection and disposal of the resulting products. The invention is especially useful for the destruction of chlorofluorocarbons.
