Kinetic Prediction of Fast Curing Polyurethane Resins by Model-Free Isoconversional Methods. [PDF]
Polymers (Basel), 2018 In this work, the characterisation of reaction kinetics of a methylene diphenyl diisocyanate (MDI)-based fast curing polyurethane resin (PUR) and the mathematical description of its curing process are presented. For the modelling of the reaction process isoconversional methods, which are also called model-free approaches, are used instead of model ...

Critical study of the isoconversional methods of kinetic analysis [PDF]
Journal of Thermal Analysis and Calorimetry, 2008 A critical study of the use of isoconversional methods for the kinetic analysis of non-isothermal data corresponding to processes with either a real or an apparent variation of the activation energy, E, with the reacted fraction, α, has been carried out using for the first time simulated curves.

Thermogravimetric analysis of face mask waste: Kinetic analysis via iso-conversional methods [PDF]
MATEC Web of Conferences, 2023 The surge of face mask waste in response to the global pandemic has proven to be a liability to the environment. Microfibers from plastic constituents of the face mask would cause microplastic pollution in the water bodies. Fortunately, these waste could

Thermogravimetric analysis of high-density cork granules using isoconversional methods
Energy Reports, 2022 In the present work thermogravimetric techniques were used to study the thermal degradation of high-density cork granules. Pyrolysis experiments were carried out for four heating ramps (10, 15, 20 and 25 °C.min−1), using nitrogen as the carrier gas. From

Kinetic compensation effect of isoconversional methods [PDF]
Reaction Kinetics, Mechanisms and Catalysis, 2020 AbstractFor experimental data obtained under different reaction/process conditions over time or temperature, the kinetic compensation effect (KCE) can be expected. Under dynamic (nonisothermal) conditions, at least two analytical pathways forming the KCE were found.
