Published in 2017 at "Energy Conversion and Management"

DOI: 10.1016/j.enconman.2017.07.059

Abstract: Abstract The purpose of this study was to investigate the effect on polystyrene (PS) during co-pyrolysis with biomass through thermal decomposition. The model-free iso-conversional methods (Kissinger, Friedman, Flynn-Wall-Ozawa, Kissinger-Akahira-Sunose, Starink and Vyazovkin) were adopted to… read more here.
