With increasing automobile ownerships in China, the number of end-of-life vehicles has also rapidly increased. However, the automobile shredder residue generated during the dismantling of end-of-life vehicles in China is not treated properly and has caused great resource waste and environmental problems. In this work, automobile shredder residue from a domestic end-of-life vehicles dismantling company was comprehensively studied through element analysis, combustion heat experiment, proximate analysis, and thermogravimetric analysis. The feasibility of using pyrolysis combined with gasification to treat and recycle automobile shredder residue was investigated. The produced gas, oil, and residue yield was measured and the correlation between their yield and the experimental temperature and ratio of air to automobile shredder residue feed was studied. It is found that when ratio of air and experimental temperature are 1.5 mol kg−1 and 900 °C, respectively, the heat energy of the gas produced per kilogram treated automobile shredder residue reaches a maximum value of 11.28 MJ. The characteristics of pyrolysis oil and solid residue were studied. The solid residue takes up 4.65%~5.57% of the original end-of-life vehicles weight. This greatly helps to reach the target of a 95% recycling rate.
