Thermal degradation of virgin and waste plastics: Estimation of kinetic and thermodynamic parameters using model‐free iso‐conversional methods

“…The reaction rate model that best describes the data may be identified from a master plot constructed with the values of g (α), using different reaction models and the experimental results obtained from iso‐conversional model 26–27 . At the reference point (50% conversion), $$$$\begin{equation}g\left( {\alpha = 0.5} \right) = \frac{{A{E_a}}}{{\beta R}}\;p\left( {{x_{\alpha = 0.5}}} \right)\end{equation}$$$$…”

“…θ expt or $$[ {\frac{{p( x )}}{{p{{( x )}_{\alpha = 0.5}}}}} ]$$ (Equation 23) was computed from the values of p ( x ) and p ( x ) α =0.5 calculated by the respective iso‐conversional method. For an appropriate reaction‐rate model, the experimental points ( α , q expt ) should lie on the theoretical master‐plot of θ model vs α 8,26,27 …”
