Recycle system for worthless or useless material

Abstract

A recycle system for a worthless or useless material, characterized in that the worthless or useless materials is subjected to pyrolysis to form a carbonized components, a gaseous component from the worthless or useless material is cooled and liquefied, and the liquefied product is fractionated to produce a useful material. The recycle system allows the production of useful material from a worthless or useless material at a lower cost as compared to a conventional system.

What is claimed is:  
     
         1 . A recycle system of unnecessary material wherein a carbonized component is obtained by thermal decomposition of unnecessary material, and a vaporized component from the unnecessary material is cooled and liquefied, and the cooled and liquefied component is fractionated and a useful substance are taken out therefrom.  
     
     
         2 . The recycle system according to  claim 1 , wherein a less liquefiable vaporized component is fluxed and used as a heat source for thermally decomposing the carbonized component.  
     
     
         3 . A carbonized component obtained by the recycle system according to  claim 1  or  2 .  
     
     
         4 . A useful substance obtained by the recycle system according to  claim 1  or  3 .
