It is very important to examine the effect of pre-oxidation of coal on its carbonization behavior from various aspects. In this study, the carbonization reaction of oxidized coal has been examined. The coal was oxidized at 250, 270 and 300℃ by air, then carbonized at 900℃. The gas formation rate and weight change during the carbonization of the pre-oxidized coal were measured continuously using a mass spectrometer and a thermogravimetric analyzer, respectively. The changes in the functional groups of the coal during the carbonization were measured by in-situ FTIR. From these measurements the mechanism of the carbonization was discussed.
