Thermal degradation studies and kinetic modeling of cardoon (Cynara cardunculus) pyrolysis using thermogravimetric analysis (TGA).

TL;DR: A variance in the activation energy with conversion was observed when the KAS and OFW models were employed, which reveals that the pyrolysis of cardoon progresses through more complex and multi-step kinetics.

TL;DR: In this article, a classification of model-free isoconversion methods for the calculation of activation energies of thermally activated reactions is proposed, by deriving expressions for the main sources of error which includes the inaccuracy in reaction rate measurement, approximations for the temperature integral and inaccuracies in determination of temperature for equivalent fraction transformed.

TL;DR: In this paper, the authors show which of four abbreviated series approximations most nearly approaches this ideal, and show that the best balance of accuracy and convenience is achieved by the use of series taken to as few terms as possible.
Abstract: THE equation of the plot of thermogravimetric data is useful in kinetic analysis (1–12), but since it contains an exponential integral, many workers prefer approximate expressions. The best balance of accuracy and convenience is achieved by the use of series taken to as few terms as possible, and it is the purpose of this communication to show which of four such abbreviated series approximations most nearly approaches this ideal.
