Using Isothermal Kinetic Results to Estimate the Kinetic Triplet of Catalytically Cracking of HDPE

The Arrhenius parameters and the reaction model of catalytically cracking of high-density polyethylene (HDPE) have been estimated from isothermal kinetic results. We introduced a new catalyst that is able to convert waste plastics to fuel oil and introduced new method to record mass decrease with time under pure static condition. A best fit of the theoretical reduced-time plot (RTP) to an experimental one led to the conclusion that ‘contracting cylinder’ model would represent the HDPE catalytically cracking.
