Title Apparatus for converting both halogens in organic halides and organic compounds to inorganic substances
Abstract (US6893616)
A bed of calcium oxide and/or barium oxide in particulate form is continuously moved through a contact reaction zone such that it enters into countercurrent reaction with the feedstock and the reaction is performed in a reaction column equipped with an agitating/moving device by which the halide which is the product of reaction between the organic halide and the oxide is continuously discharged to the outside of the reaction zone.
Scope of claims [claim1]
1. In an apparatus in which a feedstock containing an organic halide either alone or in a mixture with an organic compound is gasified or atomized and subjected to the reaction with calcium oxide, barium oxide or a mixture thereof that are heated at 400-700 deg. C., whereby the halogen in the organic halide is converted to a calcium halide and/or a barium halide, the improvement comprising:
a) a means for gasifying or atomizing the feedstock containing the organic halide either alone or in admixture with the organic compound;
b) a heating means for heating the particles of calcium oxide and/or barium oxide at a controlled temperature of 400-700 deg. C.;
c) a means for supplying the particles of calcium oxide and/or barium oxide continuously;
and d) a reaction column equipped with a supply section for the feedstock as supplied from said gasifying or atomizing means and which contains the organic halide either alone or in admixture with the organic compound, a reactive section which is heated by said heating means and in which a moving bed of said oxide particles is continuously brought into countercurrent reaction with said feedstock so that the halogen in the organic halide is converted to a calcium halide and/or a barium halide, and an agitating/moving means by which said resulting calcium halide and/or barium halide is continuously discharged to the outside of the reaction system.
