Abstract
A process for the safe and efficient disposal of toxic chlorinated hydrocarbon waste materials in which the chlorinated hydrocarbon is brought into close surface contact with a finely divided para- or ferromagnetic material, such as a fluidized bed of iron powder, in the presence of high intensity microwave radiation, so as to effect an electron transfer reaction which yields chloride anions, which subsequently react with the iron to form ferrous chloride, and an organic radical which is readily oxidized, in the presence of gaseous oxygen, to carbon dioxide and water.
Claims8
A process for disposal of chlorinated hydrocarbons comprising:
- effecting intimate contact between a para- or ferromagnetic material surface and a solid or liquid phase chlorinated hydrocarbon;
- subjecting said intimately contacted surface to microwave radiations in the range 1.5-3 GHz so as to generate a high intensity oscillating electrical field at said surface and so as to produce, in the presence of a free oxygen containing gas, chloride ions and oxidation products of organic moieties of said chlorinated hydrocarbons.
A process for disposal of chlorinated hydrocarbons comprising:
- adsorbing a solid or liquid phase chlorinated hydrocarbon onto a finely divided para- or ferromagnetic material surface;
- subjecting said material surface with adsorbed said chlorinated hydrocarbon to microwave radiations in the range 1.5-3 GHz so as to generate a high intensity oscillating electrical field and so as to produce, in the presence of a free oxygen-containing gas, chloride ions and oxidation products of organic moieties.
