Abstract |
The growing global plastic waste challenge requires development of new plastic waste management strategies, such as pyrolysis, that will help to enable a circular plastic economy. Developing opti-mized, scalable pyrolysis reactors capable of maximizing the yield of desired products requires a fundamental understanding of plastic pyrolysis chemistry. Accordingly, the intrinsic reaction kinetics of polypropylene pyrolysis have been evaluated by the method of pulse-heated analysis of solid reactions (PHASR), which enables time-resolved measurement of pyrolysis kinetics at high tempera-ture absent heat and mass transfer limitations on the millisecond scale. Polypropylene pyrolysis product evolution curves were generated at 525 degrees C-625 degrees C, and the overall reaction kinetics were described by a lumped first-order model with an activation energy of 242.0 +/- 2.9 kJ mol-1 and a pre-exponential factor of 35.5 +/- 0.6 ln(s-1). Additionally, the production of solid residues formed during polypropylene pyrolysis was investigated, revealing a sec-ondary kinetic regime. |
