Insights into the evolution mechanism of polyethylene pyrolysis: a combined experimental ReaxFF-MD and DFT study
Abstract
Plastic pyrolysis is a promising technology for converting plastic waste into valuable fuels and chemicals; however, insufficient understanding of reaction mechanisms and kinetics limits reactor design and industrial application. In this study, the pyrolysis of polyethylene (PE) was systematically investigated through a combination of experiments with ReaxFF molecular dynamics (ReaxFF-MD) simulations and density functional theory (DFT) calculations. Experimental results for C 6 -C 29 products show that PE pyrolysis at 500 °C mainly yields wax (79.76 %) and oil (
