To provide a thermal decomposition method in which waste plastics (hereafter referred to as "mixed waste plastics"), a mixture of a thermoplastic resin containing chlorine as a compositional component and a thermosetting resin, are mixed with alkaline powders and are subjected to thermal decomposition at relatively low temperature in a simplified brief processing step, thereby efficiently obtaining an oil component having significantly low level of chlorine and also preventing corrosion of equipment caused by hydrogen chloride, and an apparatus used for the method.
The thermal decomposition method of mixed waste plastics has structure in which the mixed waste plastics are contacted and mixed with the alkaline powders in a reactor, are subjected to thermal decomposition and gasification while being purged with inert gas by heating until the temperature inside the reactor is 200-700°C by an induction heating apparatus using high frequency electric current, thereby obtaining the oil component having low level of chlorine and recovering the chlorine component contained in the mixed waste plastics as alkali metal salts.
