Distributed Activation Energy Model for Thermal Decomposition of Polypropylene Waste
Summary
This study analysed the pyrolysis kinetics of waste polypropylene plastic using the Distributed Activation Energy Model, finding that decomposition follows a Gaussian distribution. The research supports the development of better thermal recycling processes for one of the most commonly discarded plastic types.
Abstract Thermal decomposition kinetics of Polypropylene (PP) waste is extremely important with respect to valorisation of waste plastics and production of utilizable components viz. chemicals, fuel oil & gas. The present research study focuses on pyrolysis kinetics of PP waste, which is present as a fraction of municipal plastic waste through distributed activation energy model (DAEM). The decomposition kinetics for PP follows a Gaussian distribution, where the normal distribution curves were centred corresponding to activation energy of 224 kJ/mol. The standard deviation of the distribution for the PP sample was found to be 22 kJ/mol indicating its wider distribution of decomposition range. The data validation has been carried out by comparing the rate parameter and extent of conversion values calculated through DAEM model with the Thermogravimetric analysis (TGA) experiments carried out for PP at various heating rates of 5, 10, 20 and 40 °C/min.
