다국어 초록 (Multilingual Abstract)
The organic oxygen content in coal has been known very important for analyzing the structutre and reactivity
of coal in coal conversion processes. FNAA and ASTM, chemical analyses, and flash pyrolysis methods were
used for this and their results were compared and explained. The comparison of organic oxygen content of
coals determined by ASTM using modified Parr formula and FNAA methods showed a close agreement. The
organic oxygen contents(expressed as carboxyl, hydroxyl and carbonyl groups) of coals determined by chemical method decreased with increasing coal rank. The evolution of organic oxygen content during pyrolysis of Wyodak subbituminous coal increased with increasing temperature and the total organic oxygen content in sample was completely pyrolyzed at around 1000 oC.
