%0 Journal Article %T Using Isothermal Kinetic Results to Estimate the Kinetic Triplet of Catalytically Cracking of HDPE %A Mohammad Reza Shishesaz %A Mohammad Hossein Madahi %J American Journal of Oil and Chemical Technologies %D 2013 %I Petrotex Publication Group %R 10.14266 %X 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. %K Catalytically Cracking %K Isothermal Kinetics %K HDPE %K Reaction Model %K Contracting Cylinder Model %U http://www.petrotex.us/wp-content/uploads/2013/06/Vol-1-Issue-3.pdf
