Abstract

The main problems of the kinetic description of the coal pyrolysis process have been discussed. A few possible methods for estimating the kinetic parameters of the process, on the basis of thermogravimetrical analysis in non-isothermal conditions have been presented.

Zusammenfassung

Es werden die Hauptprobleme der kinetischen Beschreibungsweise von Kohlenpyrolyseprozessen besprochen und einige mögliche Methoden zur Abschätzung der kinetischen Parameter des Prozesses auf der Basis thermogravimetrischer Analyse unter nichtisothermen Bedingungen dargelegt.
