Özet:

This study is about the thermal pyrolysis of low-density polyethylene (LDPE), which has the highest waste volume in the polyolefins plastic class, and aluminum-containing composites (C/LDPE), which are frequently used in packaging, to recover value-added products and then characterize the products obtained. LDPE and C/LDPE wastes were examined by proximate analysis, elemental analysis and TGA, and then pyrolyzed in a fixed bed reactor at different temperatures (400-600-800 ℃) and different heating rates (5-10-20 ℃/min). Afterwards, the wastes were pyrolyzed at 600 °C and 20 °C/min heating rate with zeolite catalysis and the effect of the catalyst on the liquid product was evaluated. GC-MS, FT-IR and 1H-NMR analyzes of the pyrolytic liquid products and commercial waxes were performed to determine the potential of the obtained liquid product to be used as a wax. According to the results, the product obtained from waste C/LDPE is similar to commercial heavy wax.
