Simultaneous thermogravimetric–mass spectrometric study on the pyrolysis behaviour of different rank coals

Simultaneous thermogravimetry–mass spectrometry was used to study the pyrolysis behaviour of an anthracite and three bituminous coals of different volatile matter content. This system was optimised by using calcium oxalate as a reference for calibration. A normalisation method that permitted a semiq...
