摘要: Abstract An overview is given of the possibilities thermal analysis and in particular thermogravimetry has studying low-temperature oxidation coal. First, procedures are described with which representative samples coal can be obtained. Secondly, oxygen consumption been measured using a sensitive vacuum microbalance, coupled to mass spectrometer analyze effluent gas. Finally, infrared spectroscopy structural changes at surface, due determined.
