Özet

Pyrolysis of polystyrene (PS) plastic waste was investigated in this experimental work harnessing a pressured autoclave surrounded by a furnace. PS was thermally degraded with various organic compounds, such as phenol, quinone, naphthalene, and diphenylamine. Experiments varied the temperature between 350 and 450°C. The main products of PS waste pyrolysis were mainly styrene monomer, ethyl benzene, toluene, and methyl styrene. The product spectrum can be described as a function of pyrolysis temperature and used organic compounds. The yield styrene of liquid products at various temperatures and at 400°C and 60 min with organic compounds were about from 60 to 74%. The optimum pyrolysis temperature to maximize styrene monomer yield (about 60%) was 400°C, and the maximum styrene yield was obtained with naphthalene as 74% in this study. The amount of styrene was found to increase in the following order: diphenylamine < thermal < phenol < quinone < naphthalene.
