“…For example, by increasing the heating rates from up to °C min −1 , the peak reaction rates observed were 0.0051, 0.0077, 0.0104, and 0.0159 s −1 , respectively. In all of the four heating rates used (10,15,20, and 30 °C min −1 ) for the prediction, the reaction profile and reaction rate curves appeared to be consistent.…”

“…The results herein are lower than those reported by Yao et al [36], who reported 184-269 kJ mol −1 . This is maybe due to the fact that they did not specify the plastic waste that they used along with the high heating rates used (15,25, and 35 °C min −1 ).…”

“…There are mainly four different technologies in dealing with plastic waste management which are: re-extrusion that requires semi-clean plastic scrap, along with mechanical (physical), chemical (solvolysis and pyrolysis), and energy recovery (incineration) [2,12,13]. Lopez et al found out that the variability and inconsistency of the feed composition was the major challenge along with catalyst deactivation [14][15][16].…”

Background: Recycling the ever-increasing plastic waste has become an urgent global concern. One of the most convenient methods for plastic recycling is pyrolysis, owing to its environmentally friendly nature and its intrinsic properties. Understanding the pyrolysis process and the degradation mechanism is crucial for scale-up and reactor design. Therefore, we studied kinetic modelling of the pyrolysis process for one of the most common plastics, polyethylene terephthalate (PET). The focus was to better understand and predict PET pyrolysis when transitioning to a low carbon economy and adhering to environmental and governmental legislation. This work aims at presenting for the first time, the kinetic triplet (activation energy, pre-exponential constant, and reaction rate) for PET pyrolysis using the differential iso-conversional method. This is coupled with the in-situ online tracking of the gaseous emissions using mass spectrometry. Results: The differential iso-conversional method showed activation energy (E a) values of 165-195 kJ mol −1 , R 2 = 0.99659. While the ASTM-E698 method showed 165.6 kJ mol −1 and integral methods such as Flynn-Wall and Ozawa (FWO) (166-180 kJ mol −1). The in-situ Mass Spectrometry results showed the gaseous pyrolysis emissions, which are C 1 hydrocarbons and H-O-C=O along with C 2 hydrocarbons, C 5-C 6 hydrocarbons, acetaldehyde, the fragment of O-CH=CH 2 , hydrogen, and water. Conclusions: From the obtained results herein, thermal predictions (isothermal, non-isothermal and step-based heating) were determined based on the kinetic parameters. They can be used at numerous scale with a high level of accuracy compared with the literature.

“…[54] There are many reviews that cover the pyrolysis, hydrocracking, and gasification of plastic waste with emphasis on the technique (i. e., operating conditions) and specific end product. [5,11,23,[27][28][29][30][31][32][33][34][35][36][37][38][39][41][42][43][44][45][46][47][48][49][50][51][52][54][55][56][57][58][59][60][61][62][63] Here, we present a comprehensive review of the various catalysts that have investigated for PSW conversion, focusing on the effects of catalyst properties on the outcome of the plastic conversion. This review aims to draw a connection between the impact of the textural properties of the catalyst and its performance for plastic conversion with hopes that this can be a useful resource for the development and design of future improved plastic waste conversion catalysts.…”
