Chemical recycling of plastic materials: kinetic modelling of the thermal degradation of PET
Current challenges in management of solid plastic wastes motivates the renovated interest in better assessing the chemistry and the physics involved in thermal processes such as pyrolysis to directly produce chemicals, and gasification, to produce valuable syngas that can be re-used for energy or fuels.
This thesis aims at developing a detailed kinetic model for the thermal degradation of polyethylene terephthalate (PET), extending the existing kinetic framework for polyethylene (PE), polypropylene (PP), polystyrene (PS) and polyvinylchloride (PVC). The new kinetic subset, coupled with previously developed models will allow for simulations of real mixtures of plastic materials collected in municipal solid wastes (Plasmix).
