1-10　Reexamination of the so-called “Distributed Activation Energy Model” for the kinetic analysis of pyrolysis reaction

Abstract

Miura¹⁾ and Miura and Maki²⁾ presented a method to estimate the distribution function of activation energy and frequency factor, f(E) and k₀(E), in the so-called “Distributed Activation Energy Model (DAEM)” from 3 sets of TPR data at least. The method was reexamined and a more generalized interpretation on the method was given. It shows that E vs x_B^* and k₀ vs x_B^* relationships are natural and more general representations of the parameters of DAEM, where x_B^* is the normalized amount of solid reactant. The additional procedure was also proposed to increase the accuracy of the k₀ vs x_B^* relationship.
