The kinetic study of pyrolysis involved the use of a homemade
thermogravimertic analysis (TG) system and showed that the reaction is
first order at high temperature range (390- 450) ºc.
The reaction rate constant has been increased with temperature
(0.15903- 0.9183) min-1 at the same range of temperature above according
to Arrhenius model equation modeled Bovier and Gelus, which can be
used to estimate the kinetic parameters .the activation energy of reaction
is found to be 1.33 kcal/mol. , whereas the frequency factor is equal to 1x
10-8 l/mol. sec.
From comparison between theoretical and experimental conversion due to
the same model above it could be seen that there is a good agreement
between theoretical and experimental results and higher temperatures
(390-450) ºc but become worse of low temperatures (200-350) ºc.
