Abstract

This study investigated the conversion of oil products from polypropylene by using dispersed Co and Mo catalyst on reaction time and concentration change for knowledging liquefation characteristics at low-temperature (425, 450 and $475^{\circ}C$) pyrolysis in a batch reactor. The reaction time was set in 20~80 minutes and the oil products formed during pyrolysis were classfied into gas, gasoline, kero, diesel and heavy oil according to the domestic specification of petroleum products. The pyrolysis conversion rate was showed as Mo catalyst > Co catalyst > Thermal in all reaction time at reaction temperature $450^{\circ}C$. The conversion rate and yields of the pyrolysis products were the most height when Co and Mo Catalyst ratio was 50:50.

본 연구는 폴리프로필렌(PP) 수지의 Co 및 Mo 촉매에 의한 반응시간과 농도변화에 따른 저온열분해 액화특성을 파악하고자 회분식 반응기를 이용하여 특정 온도(425, 450, $475^{\circ}C$)에서의 전환율을 측정하였다. 열분해 시간은 20~80분으로 설정하였고 생성물은 산업통상자원부에서 고시한 증류성상 온도에 따라 가스, 가솔린, 등유, 경유, 중유로 분류하였다. 그리고 $450^{\circ}C$ 반응온도에서 촉매 사용에 따른 전환율은 모든 반응시간에 있어 Mo 촉매 > Co 촉매 > 무촉매 순이었다. Co 및 Mo 촉매 농도별 PP 전환율 및 열분해 생성물 수율은 Co:Mo=50:50 혼합시 가장 우수한 것으로 나타났다.
