Abstract

Polyethylene wax was obtained from pyrolysis experiments on Low Density Polyethylene (LDPE) wastes using a muffle furnace in inert condition. 60 – 80% of the initial mass of wax were obtained as heating was added at a rate of 10oC/min. Operating conditions for the reaction were 400 – 450oC over time of 30 – 50min and effects of these parameters were discussed. Using Friedman’s iso-conversional model, the kinetic parameters - activation energy, pre-exponential factor and frequency factor were 58.71kJ/mol, 13.726E+12/s and 914378.61 respectively. Also, spontaneity of LDPE pyrolysis occurs at high temperatures and these were validated from the calculated thermodynamic parameters.
