Pyrolysis behavior and kinetic analysis of waste polypropylene-based complex for cable filler

To better understand the thermochemical conversion for pyrolysis recycling of cable waste, kinetics typical filler was investigated in detail. Thermogravimetric experiments were conducted at different heating rates ranging from 5 °C/min−1 to 40 °C/min−1. Three degradation stages observed process pyrolysis. The influence air on superposition first two peaks also identified. activation energy calculated using three commonly used model-free methods. A three-component reaction scheme proposed describe whole process. one associated with stearic acid decomposition, second dominated by polypropylene while third attributed calcium carbonate decomposition. created model combined an optimization algorithm applied determine kinetic parameters. values estimated this method accordance those isoconversional methods, which verified accuracy parameter calculation algorithm. predicted results based optimized parameters agreed well experimental data. Finally, deconstructed into independent reactions corresponding all reactants and products.
