Comparison of waste plastics pyrolysis under nitrogen and carbon dioxide atmospheres: A thermogravimetric and kinetic study

• Thermogravimetric analysis of individual plastics and mixed under N 2 , CO mixture /CO atmospheres. Kinetic parameter for all samples were identified by using modified Coats-Redfern technique. in the reacting gas reduced amount residue. Low activation energy was atmosphere with a ratio 7:3. It is important to understand influence pyrolysis on thermal degradation waste plastics. In this study, decomposition plastics; high low density polyethylene, polypropylene, polystyrene, polyethylene terephthalate investigated from ambient temperature 500 °C within nitrogen or carbon dioxide The characteristics kinetic parameters (household packaging, building construction agricultural plastics) three different treatment plants atmospheres, only one peak observed between 250?510 °C. replacement showed effects energy. Mixtures resulted lower plastic samples, exception polystyrene terephthalate. suggested that required process. However, more than 30 % may process due higher value residue obtained after experiment.
