Recycling. Thermal Treatment Technology of Automobile Residue. Carbonization Method.

Abstract

We have developed the technology to treat automobile shredder residue (ASR) appropriately for the nonferrous metals recycling and non ferrous metals and refining technology. In this technology, we adopted twostage-carbonization process for reducing fatal factors such as chlorine problem and difficulty of handling of ASR. In this two-stage-carbonization process, PVC is decomposed selectively for the removal of chlorine at 350°C, then the residue of the first carbonization is carbonized for the decomposition of residual plastics at 550°C. Finally, nonferrous metals contained in the ASR is recovered as metal form and organic materials such as plastics is converted to gas, oil and carbon for the utilization as fuel.
