Abstract

In this study, waste engine oil (WEO) was used as catalyst for co-pyrolysis with waste tires (WT) to increase the heat transfer efficiency between tire particles. The synergetic effects during co-pyrolysis process of WT and WEO were investigated via thermogravimetric analyzer. Co-pyrolysis of different mixing ratios blends were performed in a self-made tube furnace at 500℃ to explore the effect on product distribution. The compositions of products were determined by FTIR, Py-GC/MS, and BET. TG and DTG curves of mixture demonstrate that WEO could change the pyrolysis process of WT significantly. The main pyrolysis temperature is reduced by 50℃. The conversion of pyrolysis oil increased, and the conversion of char decreased with the addition of WEO. The yield of H2 and D-limonene increased by 5.6% and 1.85%, respectively, when 20% WEO was added. Our work gives insight into the co-pyrolysis of WT and WEO, and provides a novel route of WT pyrolysis with high efficiency and quality. [ABSTRACT FROM AUTHOR]
