Kinetic and Evolved Gas Analysis of PVC Pyrolysis by TG-MS

Abstract:

Taking the overlap of two weight loss peaks into consideration and separating them, the multiple-step model of PVC pyrolysis has been analysed by using Coat-Redfern method. It was found that pyrolysis of PVC consisted of three reactions, whose reaction models were all the second order. This method was proved accurate by comparison between simulation and experiment of TG curves. The mass spectrometry of evolved gases agreed well with the TG curves. Obviously, gases such as C₆H₆, HCl and C₂H₂ were released during PVC pyrolysis.
