N2 - Polypropylene is a significant component of mixed plastic waste from which fuels and chemicals can be recovered via thermal or catalytic degradation. Pyrolysis of polypropylene was investigated at a temperature of 420°C and reaction times ranging from 10 to 180 minutes. Total conversion reached approximately 60% at 90 minutes, and no significant change was observed for longer reaction times. The selectivity to monomer, propylene, achieved a plateau at approximately 10% after a reaction time of 90 minutes. The overall product distribution can be explained by the typical free radical mechanism with the dominant products as alkenes in the form of C3n, alkanes in the form of C3n-1, and dienes in the form of C3n-2.
