Abstract
Methods and equipment are provided for making polybichlorophenyl non-toxic. Methods include a first oxidation step, in which polybichlorophenyl is burned, and a second oxidation step, in which exhaust gas from the first oxidation step is oxidized by contact with metallic phthalocyanines or metallic phthalocyanine derivatives and with an oxygen supply compound. Equipment includes a first furnace for burning a polybichlorophenyl-containing oil with an auxiliary fuel and a second oxidation reaction unit. The second oxidation reaction unit connects to the first furnace under seal, and includes metallic phthalocyanine or metallic phthalocyanine derivative solution supply source and an oxygen supply compound supply source.
