• • Fraser-Suzuki deconvolution resolves waste tire pyrolysis into four pseudo-components with activation energies of 118.21, 202.60, 231.98, and 251.97 kJ/mol, enabling precise temperature-zone control in reactor design.
• • The asymmetric peak-fitting capability of Fraser-Suzuki achieves R²=0.998, significantly outperforming symmetric functions (Gaussian, Lorentzian, Weibull) for complex overlapping reactions, ensuring reliable kinetic parameter extraction.
• • Pyrolysis primarily occurs in the 573–773 K range, with higher heating rates inducing a thermal lag effect (TG/DTG shift to higher temperatures), critical for scaling up from lab to industrial reactors.
• • Overall and stage-wise kinetic methods fail to capture the complexity of waste tire pyrolysis; Fraser-Suzuki deconvolution provides a mechanistic breakdown essential for optimizing product yields (e.g., oil up to 41.10%) and char quality.
