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.

Özet

Plastik atıklar dünya çapında 2018 yılındaki toplam kentsel katı atıkların %18,46’sını oluşturur. Ağır hidrokarbonlar rafineri proseslerinin atığı olarak meydana gelir. Bu çalışmada, literatürde ilk defa atık polistiren köpük (PS) ve ağır aromatik atığın (HAW) eş-pirolizi yürütülmüştür. Sıcaklık (420, 450, 480 ⁰C) ve karıştırma oranının (1/5, 3/5, 1/1) sıvı ürün verimi ve pirolitik sıvıların bileşik dağılımı üzerindeki etkisini incelemek amaçlanmıştır. Tüm deneyler yarı-kesikli reaktör konfigürasyonunda azot atmosferi altında yapılmıştır. Gaz kromatografi-Kütle spektrometresi (GC-MS) pirolitik sıvıları analiz etmek için kullanılmıştır.480 ⁰C’de 1/5 HAW/PS besleme oranında maksimum sıvı verimi %87.24 olarak elde edilmiştir. Saf PS pirolizi ile karşılaştırıldığında, nispeten düşük stiren ve toluene verimi edinilmiştir. Bununla birlikte, etilbenzen ve kümen verimleri beslemeye HAW katılmasıyla artmıştır. Naftalin PS pirolizinin sıvısında tespit edilmemiştir. Maksimum naftalin verimi 480 ⁰C’de 1/5 HAW/PS besleme oranında % 12,71 olarak alınmıştır.
