본 연구는 '열매체 및 가스 순환형 열분해 시스템' 개발 목적으로 열분해 실험을 진행하기 전, 공정 모사용 기본 데이터 확보를 위해 수행되었다. 폐플라스틱 대체 물질로 폴리프로필렌(Polypropylene, PP)을 열분해 시료로 사용하였으며, 본 시스템에서 열전달 매체로 활용되는 유동사(이하 sand)를 사용하였다. 촉매 열분해 실험을 수행하기 위해 Mn계 물질(이하 Mn)을 촉매로 선택하였으며, sand에 담지하여 촉매 열분해 실험을 수행하였다. 열중량 분석기(Thermogravimetric analyzer, TGA)를 이용하여 PP의 기본 물성을 분석하였고, 질소 분위기 600℃ 조건에서 촉매 열분해를 통해 액상 오일을 생성하였다. 생성된 액상 오일은 GC/MS 분석을 통해 탄소 수 분포를 확인하였다. 본 연구에서는 Mn 담지 유무와 함량 변화에 따른 액상 오일 수율과 오일 내 탄화수소 분포에 미치는 영향을 조사하였다. Mn/sand를 이용하면 sand를 단독으로 활용한 열분해와 비교하여 잔여물이 감소하고 오일 수율이 증가하였다. 또한 Mn 함량 증가에 따라 액상 오일 내 C₆~C₉ 범위 휘발유 비율이 점차 증가하였으며, 오일 내 C₁₀보다 탄소 수가 큰 경유 및 heavy 오일 분포가 감소하는 것으로 확인되었다. 종합하면, Mn을 촉매로 활용하고 함량 변화를 통해 액상 오일 회수량을 증가시키고 생성물 내 휘발유 비율을 증가시킬 수 있을 것으로 판단하였다.

This study was conducted to obtain basic process simulation data before conducting pyrolysis experiments for the development of a thermochemical conversion system by recirculation of heat carrier and gases thereby. In this study, polypropylene (PP) was used as a pyrolysis sample material as an alternative to waste plastics, and fluid sand was used as a heat transfer medium in the system. Manganese (Mn) was chosen as the catalyst for the pyrolysis experiment, and the catalyst pyrolysis was performed by impregnating it in the sand. The basic properties of PP were analyzed using a thermogravimetric analyzer (TGA), and liquid oil was generated through catalytic pyrolysis under a nitrogen atmosphere at 600℃. The carbon number distribution of the generated liquid oil was confirmed by GC/MS analysis. In this study, the effects of the presence and the amount of Mn loading on the yield of liquid oil and the distribution of hydrocarbons in the oil were investigated. When Mn/sand was used, the residue decreased and the oil yield increased compared to pyrolysis using sand alone. In addition, as the Mn loading increased, the ratio of C6~C9 range gasoline in the liquid oil gradually increased, and the distribution of diesel and heavy oil with more carbon atoms than C10 in the oil decreased. In conclusion, it was found that using Mn as a catalyst and changing the amount of Mn could increase the yield of liquid oil and increase the gasoline ratio in the product.
