Abstract

The pyrolysis in a nitrogen atmosphere of three run-of-mine samples and a suite of lithotype samples of Victorian brown coal has been investigated using simultaneous TG/DTG/DTA. The TG, DTG curves provide parameters which represent the pyrolysis properties of coal. The pyrolysis profiles can also be used as “fingerprints” of brown coal lithotypes and hence are of value in the context of the broad characterization of coal.

Zusammenfassung

Mittels Pyrolyse in Stickstoff wurden unter Anwendung simultaner TG, DTG und DTA drei Förderproben und eine Reihe von Lithotypenproben von Viktoriabraunkohle untersucht. Die TG und DTG Kurven liefern Parameter, die für die Pyrolyseneigenschaften von Kohle charakteristisch sind. Die Pyrolysenprofile können auch als „Fingerabdruck“ von Braunkohlenlithotypen benutzt werden und sind deshalb im Zusammenhang mit einer umfassenden Charakteristik der Kohle von Bedeutung.

Резюме

Совмещенным методом ТГ, ДТГ и ДТА изучен пиролиз трех отмытых образцов и набора литотипных об разцов викторианско го бурого угля в атмосфере азот а. Кривые ТГ и ДТГ дали параметры, харак теризующие пиролити ческие свойства угля. Пироли зные профили могут быть также использов аны как «отпечатки па льцев» литотипных образцов бурого угля и могут служить оценкой обши рной характеристики угля.
