The thermal degradation rate constant of mixed plastics

摘要

The thermal degradation rate constant of plastics containing polypropylene, polyethylene and polystyrene was analysed by using the distributed activation energy model. The values of activation energy E and frequency factor #kappa#_o were widely distributed and differed between samples tested. The #kappa#_o value was well correlated with E. It is expremely important to take the E distribution into consideration in estimating the weight of un-volatilize matter accumulated in the waste plastics degradation reactor.
