Characterization of coals, other kerogens, and their extracts by thermal mass spectrometry
Description:
The objective of this study is to elucidate the nature of the medium size molecules derived from coals by a succession of stronger extraction conditions. The Argonne Premium Coals have been extracted with pyridine, binary solvents and with KOH/ethylene glycol at 250{degrees}C. Thermal desorption and pyrolysis mass spectrometry were the major approaches chosen to provide detailed information on structure and heteroatom composition. Soft ionization techniques including desorption chemical ionizat…
