Abstract: 본 발명은 폴리염화비닐(Polychlorinated biphenyl ; 이하 PCB라고 함)의 변성처리장치에 관한것이다. 
     PCB는 절연유, 열매체, 윤활유등 다용도로 사용되고있어 이용가치가 매우높고 또한 PCB는 불연성이고 또한 열변성의 우려가 없어 절연성 또는 전기적 특성이 훌륭하고 매우 화학적으로 안정하기 때문에 여러용도에 걸쳐 사용되고 있다. 
     그러나, PCB는 유독한 오염물질이므로 무해화 처리가 쉽지는 않다. 
     PCB가 환경중에 방출된 경우 난분해성 물질이므로 환경이나 생물체에 축적되어 인체에는 간기능장애, 발암성등의 영향을 일으킨다고 지적되어 왔다. 이로 인하여 PCB의 분해처리에 관하여 여러 가지의 방법이 고안되어 현재 고온소각 처리나 알칼리 촉매법 자외선 분해법등에 의하여 처리하고 있으나 PCB의 분해처리는 아직 불완전하고 PCB보다도 더욱 유독성이 높은 다이옥신류의 발생이 염려되고 있다. 
     이와같이 PCB무해화 처리는 커다란 기대가 모아지고 있음에도 불구하고 효율적이고 안전성이 높은 PCB의 무해화 처리법은 아직 발명되지 못하고 있는 실정에 놓여있다. 
     본 발명은 위와같은 문제점을 해결하기 위한 것으로서, 
     본 발명의 목적은 종래 어렵게 여겨져 왔던 PCB의 무해화를 달성할 수 있도록 하였다. 이러한 본 발명의 목적은 PCB의 무해화 싸이클의 실용화와 더불어 극히 신규성이 높고 PCB 무해화 처리에 있어서 안전성이 높은 완전히 별개의 물질로 변성(變成)처리장치를 제공함에 있다.
