Abstract: Waste engine oil (WEO), as a waste resource, has not been fully exploited. Using WEO as a reductant for copper slag cleaning is quite meaningful. Fe 3 O 4 is an important element in copper slag cleaning. So the laws of thermal cracking of WEO at different temperatures and the effect on thermal cracking of WEO in the presence of Fe 3 O 4 were investigated. The results show that the high-temperature cracking of WEO mainly produces H 2 , CO, CH 4 , CO 2, and small molecules such as C. Raising the temperature is good for the cracking of WEO. When the temperature rises from 700 °C to 1300 °C, the total amount of gases produced by cracking 700 μL of WEO increases from 177.08 mL to 1010.2 mL. At 1300 °C, the total amount of gases produced by the cracking of WEO in the presence of Fe 3 O 4 was 1408.11 mL. The result indicates that Fe 3 O 4 can promote the pyrolysis of waste oil. This research provides a novel approach to the clean utilization of WEO.
