Abstract

In this study, waste tire rubbers were pyrolyzed in a lab-scale pyrolysis plant equipped with a fluidized bed reactor in a temperature ranges of $450-650^{\circ}C$. The main object of this work is to investigate the properties of pyrolysis oil with reaction temperatures and the behavior of sulfur in the products when waste polypropylene was added for co-pyrolysis. The maximum yield of oil was about 52wt.% at the reaction temperature of $456^{\circ}C$. From GC-MS analysis, the pyrolysis oils consisted mainly of limonene, toluene, xylene, styrene, trimethylbenzene, methylnaphthalenes and some heteroatom(sulfur and nitrogen)-containing compounds. The addition of waste polypropylene resulted in decrease in sulfur contents of the pyrolysis oils.

본 연구에서는 폐타이어의 열분해 특성을 알아보기 위하여 유동층 반응기를 이용하여 450에서 $650^{\circ}C$ 범위에서 급속 열분해를 실시하였다. 반응 온도의 변화에 따른 열분해 오일의 특성을 관찰하고 특히 폐폴리프로필렌을 폐타이어와 혼합하여 열분해를 실시할 때 열분해 부산물 내 황의 거동을 살펴보았다. 열분해 오일의 수율은 반응 온도 $456^{\circ}C$에서 약 52wt.%로 가장 높게 나타났다. 생산된 오일의 GC-MS 분석 결과 반응 온도가 증가할수록 지방족 화합물의 함량은 줄어드는 반면 방향족 화합물의 함량이 급격히 증가하는 것으로 나타났다. 주요 화합물은 리모넨(Limonene), 톨루엔(Toluene), 자일렌(Xylene), 스타이렌(Styrene), 트리메틸벤젠(Trimethylbenzene) 그리고 메틸나프탈렌류(Methylnaphthalenes)이었으며 미량의 황 화합물과 질소 화합물도 검출되었다. 폐폴리프로필렌을 폐타이어와 혼합 열분해 한 결과 열분해 오일 내 황의 함량이 급격히 감소하는 것을 관찰할 수 있었다.
