A Study on Pyrolysis of Pretreated Automotive Shredder Residue—Thermochemical Calculations and Experimental Work

The automotive shredder residue (ASR) is generated as an inevitable waste after the shredding process of end-of-life vehicles. Typically, ASR ends up in a landfill absence any existing processing options. comprises rubber, wood, plastics, textile, metals, and other materials, such paint glass (10%), which can be recycled reused. Given these attributes, potential feedstock for energy production metal recovery. In this study, was first pretreated because untreated (as received) fluffy heterogeneous and, therefore, difficult to feed into reactor. Subsequently, pyrolysis conducted with From thermochemical calculations, optimized temperature 500°C chosen ensure that metals would not further oxidized polymers could separated from form volatile gases, oil, char. Bench-scale tests were on integrated continuous stirred tank reactor–distillation column system. product gas composition had hydrogen methane content 30% 26% (v/v), respectively, contributing heating value obtained. oil distilled using fractional distillation apparatus gasoline diesel-grade products. physicochemical characterization its distillates also carried out. equilibrium predictions showed similar trend experimental results. addition, residual char analysis indicated presence significant amount metals—silicon, titanium, aluminum, iron. Thus, work information fuel insights recovery recovered
