Abstract


An iterative algorithm of thermokinetic constants estimation was developed for researched pyrolysis process, considering the selected mathematical model of pyrolysis, by experimental data obtained in scope of thermogravimetic experiment. Estimation of thermogravimetric constants was completed for several experiments, by application of the algorithm and manual selection of temperature range for calculations. The theoretical graph of mass loss speed was plotted, considering the calculated preexponential factor and activation energy and selected pyrolysis model. Conclusion about suitability of selected mathematical model of pyrolisys and thermokinetic parameters estimation method was done, by comparison of theoretical and experimental plot of mass loss.
