An innovative method for isothermal and non-isothermal predictions of complex reactions

In this study, we introduced a novel technique that factorizes the reaction rate of complex reactions into a temperature-dependent rate constant and a conversion function using multiple linear regression on isoconversional kinetic data. In simulated reactions, our method demonstrated higher accuracy compared to model-free approaches. Furthermore, the new method exhibited satisfactory accuracy in non-isothermal predictions of polyethylene thermal decomposition, all without necessitating the computation of Arrhenius parameters. However, the new method enables the assessment of the Arrhenius parameters, the activation energy and preexponential factor, in complex reactions as well. The accuracy of this method is confined to the experimentally explored temperature range, necessitating cautious extrapolation for temperatures beyond this interval.
