In this work, simultaneous thermogravimetric-mass spectrometric (TG-MS) analysis was used to study the release of various nitrogen compounds during pyrolysis of different-rank coals. The influence of coal rank on the evolution of volatile compounds was also considered. In addition, a series of coal chars with different burn-off degrees were obtained in a bench-scale fluidized bed reactor, using the same parent coal. The evolution of gaseous compounds arising from the thermal treatment of the partially burned chars was studied in the TG-MS system. It was found that the different chemical structures of the chars exerted some influence on the evolution of the gaseous compounds during the devolatilization process. In addition, devolatilization tests were conducted in a bench-scale fluidized bed reactor. During these tests, special attention was given to the formation of N₂O.
