A kinetic analysis of the thermochemical conversion of solid fuels (A review)

Resumo

The overview is focused on methods for the processing of kinetic curves (with and without models). The paper demonstrates that the kinetics of thermochemical conversion of solid fuels can be described by a great number of kinetic processing methods, which lead to inconsistent estimates of kinetic coefficients. They give a rather simple approximation of experimental thermogravimetric curves. However, the kinetic triplet to be determined (activation energy, order of reaction, and preexponential factor) depends on the conditions of thermoanalytical studies and (to a greater extent) on the reactivity of the test fuels.
