Unlike many previous studies that focused on single-polymer kinetic models or employed simplified reaction schemes, this study develops an enhanced multistep reaction network that explicitly considers both primary decomposition and secondary cracking pathways, thereby improving the accuracy of product distribution predictions. By integrating this detailed reaction framework with a robust nonlinear regression approach using LSQNONLIN and ODE45 solvers in MATLAB, the study achieved greater accuracy in estimating kinetic parameters than traditional curve-fitting methods. The findings reveal that HDPE exhibits the highest activation energy (222.97 kJ mol<sup>−1</sup>), indicating it is more thermally stable than LDPE (193.44 kJ mol<sup>−1</sup>) and PP (62.16 kJ mol<sup>−1</sup>). One of the highlights of the present work is that lower pyrolysis temperature (400 °C) is found to be optimum for liquid yield by reducing secondary cracking, which aligns with the sustainable fuel production principles. The study also emphasizes on the limitations of previous lumped models that overlooked wax decomposition pathways, which are crucial for optimizing the hydrocarbon distribution. Future research should investigate catalytic interventions and reactor design modifications to enhance the product selectivity and scalability.

Key results include a linear increase in conductivity (4.1–15.2 mS/cm) and opposing relaxation time trends (bulk τ<sub>1</sub> decreasing, interfacial τ<sub>2</sub> increasing), highlighting the interplay between ion mobility and electrode effects. The Debye screening length followed κ<sup>−1</sup> ∝ c<sup>−1</sup>/<sup>2</sup> (A = 0.3036), confirming theoretical predictions, while derived ionic mobilities (4.25–5.25 × 10<sup>−8</sup> m<sup>2</sup>/V·s) and diffusivities (1.09–1.35 × 10<sup>−9</sup> m<sup>2</sup>/s) captured non-ideal behavior at moderate concentrations. This work provides a robust experimental framework linking macroscopic measurements to microscopic ion dynamics, offering insights for optimizing electrochemical systems.</div></div>","PeriodicalId":17276,"journal":{"name":"Journal of the Indian Chemical Society","volume":"102 11","pages":"Article 102121"},"PeriodicalIF":3.4,"publicationDate":"2025-09-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145156029","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
