Pyrolysis Kinetics of Four Typical Kinds of Plastics

摘要

Four typical kinds of plastics were chosen to study the thermal degradation kinetics by the thermogravimetric analysis. The kinetic parameters of pyrolysis were determined with the nth-order model. The simulated results showed that there was only one obvious weight loss process during the pyrolysis of PET and PS, while there were two and three obvious weight loss processes for PE and PVC, respectively.Consequently, the nth-order model simulated the pyrolysis processes for four kinds of plastics with satisfactory agreement.
