Kinetic and Thermodynamic Study on the Pyrolysis of Low Density Polyethylene in the Production of Polyethylene Wax

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