Abstract
Plastic wastes forms 18.46 % of total municipal solid wastes in 2018 around the world. Heavy hydrocarbons occur as the waste of refinery processes. In this study co-pyrolysis of waste polystyrene foam (PS) and heavy aromatic waste (HAW) was carried out for the first time in literature. It was aimed to investigate the effect of temperature (420, 450, 480 ⁰C) and mixing ratio (1/5, 3/5, 1/1) on liquid product yield and compound distribution in the pyrolytic liquids. Whole experiments were done in semi-batch reactor configuration under nitrogen atmosphere. Gas chromatography-Mass spectrometry (GC-MS) was utilized to analyze the pyrolytic liquids. At 480 ⁰C it was obtained maximum liquid yield as 87.24 % in 1/5 HAW/PS feedstock ratio. Compared to the pure PS pyrolysis, it was achieved relatively low styrene, toluene yield. However yields of ethyl benzene and cumene increased with HAW adding to the feed. Naphthalene was not detected in liquid of PS pyrolysis. Maximum naphthalene yield was taken as 12.71% at 480 ⁰C with 1/5 HAW/PS feedstock ratio.Keywords
