METHOD FOR PYROLYSIS TREATMENT OF WASTE PLASTIC AND APPARATUS AND FUEL

摘要

PROBLEM TO BE SOLVED: To provide a method for pyrolysis treatment of waste plastics by which a low-viscosity pyrolysis oil of good quality can be obtained and an apparatus therefor. SOLUTION: The method for pyrolysis treatment is to pyrolyze the waste plastics in an oil. In the method, contained chlorine is evaporated and removed and pyrolysis is advanced so as to suppress the production of organic volatiles by using the density of the resultant melt oil produced by the pyrolysis as an index. The pyrolysis oil is recovered without separating light organic components by distillation. The density of the melt oil is preferably controlled to≥300 kg/m3to≤700 kg/m3to carry out the pyrolysis.
