Description
Summary:Automobile Shredder Residue (ASR) shows a broad chemical composition owing to the presence of different materials, and its high organic content makes it interesting as a source of energy. In this work, a bench scale two-stage reactor is used for gasifying ASR. The reactor shows an efficient ASR gasification, avoiding the formation of difficult to manage char and tar and allowing an easy recovery of energy. The results of the investigation were used to test a simple model based on mass and energy balances and chemical equilibrium, predicting syngas composition including the presence of problematic elements such as sulphur and chlorine. Gasification data calculated by the model agree in a satisfactory way with the experimental ones. Due to the large variation in ASR composition, the model predicts that ASR gasification is industrially feasible only if a blend of ASR and RDF is used as a reactor feed.
