GELENEKSEL PİROLİZ İLE ALÇAK YOĞUNLUKLU POLİETİLEN VE POLİSTİREN ATIĞINDAN KİMYASAL GERİ KAZANIMI

Abstract

Plastik atıklar Türkiye’deki toplam katı atıkların %5-14’ünü oluşturmaktadır. Plastik atıklar termoplastik ve termosetler olarak sınıflandırılmaktadırlar. Polietilen (PE), Polistiren (PS), Polipropilen (PP), Polietilen Tereftalat (PET) ve Polivinil Klorürü (PVC) kapsayan Termoplastik atıklar, mekanik geri kazanım, enerji geri kazanımı ve kimyasal geri kazanımı yöntemleri kullanılarak geri kazanılabilirler. Bir kimyasal geri kazanımı tekniği olan piroliz, yüksek verimlerde değerli kimyasalları üretmek için önem taşımaktadır.Bu çalışmada, piroliz vasıtasıyla PS ve Alçak Yoğunluklu Polietilen (AYPE)’den hidrokarbonlar elde etmek amaçlanmıştır. Ürün verimleri hesaplanmış ve sıvı ürünler GC-MS aracılığıyla analizlenmiştir. Sonuçlar göz önüne alındığında, AYPE ve PS için sırasıyla 520 ⁰C ve 570 ⁰C’nin maksimum verimlerle sıvı ürün eldesi için uygun sıcaklıklar olduğu çıkarımı yapılmıştır. Bu sıcaklık, AYPE ve PS eş-pirolizi için 570 ⁰C olarak bulunmuştur. Benzen-Toluen-Etil Benzen (BTE) fraksiyon miktarının beslemeye AYPE eklenmesiyle, PS (%88) ve AYPE/PS (%84) için neredeyse aynı sıvı ürün verimlerinde, %5’ten %30’a arttığı belirlenmiştir. Ek olarak, AYPE için tamamen alkan ve alkenlerden oluşan %70 verimle pirolitik sıvı ürün elde edilmiştir.

CHEMICAL RECOVERY FROM POLYSTYRENE WASTE AND LOW DENSITY POLYETHYLENE VIA CONVENTIONAL PYROLYSIS

Abstract

In Turkey, plastic wastes have formed 5-14 % of total solid wastes. Plastic wastes have been classified as thermoplastic and thermosets. Thermoplastic wastes which covers Polyethylene (PE), Polystyrene (PS), Polypropylene (PP), Polyethylene terephthalate (PET) and Polyvinyl chloride (PVC) can be recycled by using mechanical recycling, energy recovery and chemical recovery routes. Pyrolysis as a chemical recovery technique is important to produce invaluable chemicals in high yields. In this study, it was aimed to obtain hydrocarbons from PS and Low density Polyethylene (LDPE) via pyrolysis. Product yields were calculated and liquid products were analyzed via GC-MS. In the light of the results, it was deduced that 520 ⁰C and 570 ⁰C were the suitable temperatures to obtain the liquid product with maximum yields for LDPE and PS respectively. That temperature was found for LDPE and PS co-pyrolysis as 570 ⁰C. It was determined that Benzene-Toluene-Ethyl Benzene (BTE) fraction amount increased from 5 % to 30 % with LDPE adding in the feed for almost same liquid product yields of PS (88%) and LDPE/PS (84 %). In addition, it was obtained the pyrolytic liquid which comprised of wholly alkanes and alkenes for LDPE with 70 % product yield.
