Method and apparatus for converting both halogens in organic halides and organic compounds to inorganic substances

In a method in which a feedstock containing an organic halide either alone or in admixture 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° C., whereby the halogen in the organic halide is converted to a calcium halide and/or a barium halide, the improvement wherein a bed of calcium oxide and/or barium oxide in particulate form is continuously moved through the 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 means by which the halide which is the product of reaction between the organic halide and said oxide is continuously discharged to the outside of the reaction zone.
