Pyrolysis of solid fuels: Thermochemical behaviour, kinetics and compensation effect

“…The distribution f(E) is unknown, but it is usually assumed that a Gaussian distribution of activation energies f(E) occurs [13,31,32], then:…”

“…the mean of activation energy distribution E 0 , the standard deviation of the activation energy distribution σ and the pre-exponential factor k 0 [9,10]. Usually, it is assumed that all reactions share the same pre-exponential factor k 0 and, in order to simplify calculations, it is fixed at constant value [11][12][13][14]. Recently, in order to improve the fit of the decrease of mass curves, Cai and Liu [15] proposed considering the influence of temperature on the frequency factor.…”

Kinetic Parameters for the Thermal Decomposition of Forest Waste Using Distributed Activation Energy Model (DAEM)

“…DAEM has been recently used in the mathematical study of pyrolysis process. This model is based on the multi reaction models as it presumes that many decomposition reactions of nth-order with distributed activation energies happen simultaneously [10], [11]. The principle of the lumped kinetic model and DAEM are very similar, yet dichotomy between lumped kinetic model and distributed activation energy mode is the number of expected decomposition reactions.…”

Study of Distributed Activation Energy Model Using Various Probability Distribution Functions for the Isothermal Pyrolysis Problem

“…This model belongs to multi-reaction models. DAEM postulates that many decomposition n th order reactions with distributed activation energies occur simultaneously (Günes and Günes, 2002;Miura and Maki, 1998;Sonobe and Worasuwannarak, 2008;Dhaundiyal and Singh, 2016). Moreover, the principle concept of the lumped kinetic model has some similarity and the main demarcation is of the number of expected decomposition reactions.…”
