초록

Disclosed is a method and apparatus for pyrolytically decomposing waste plastic which may contain halogen-containing polymer such as PVC. The plastic is heated at 270.degree. to 350.degree. C., whereby a plasticizer contained in the plastic material is decomposed and vaporized, and a chlorine-containing polymer is dechlorinated to produce hydrogen chloride. The vaporized decomposition matter and the hydrogen chloride are removed from the plastic, and the vaporized decomposition matter is separated from the hydrogen chloride. Then isolated plastic is furt...

[ What is claimed is:] [1.] A method of pyrolytically decomposing a plastic material, comprising the steps of:heating the plastic material at approximately 270 to 350.degree. C., whereby a plasticizer contained in the plastic material is decomposed into a decomposition matter which is vaporized, and a chlorine-containing polymer contained in the plastic material is dechlorinated to produce a dechlorinated matter and hydrogen chloride;removing the vaporized decomposition matter and the hydrogen chloride, from the plastic material heated at the heating ste...
