The transferable hydrogen in coal is thought to play an important role in coal conversion such as coking and liquefaction. To quantify the amount of transferable hydrogen, we investigated the behavior of coal during oxidation at lower temperature such as 100-200℃. We attempted to find the correlation between weight change and change of concentration of carbonyls (by FTIR) to obtain a linear correlation between them. Consequently, we found that reactive hydrogen can be evaluated based on weight change during autoxidation by thermobalance. We are investigating the relationship between reactive amount of hydrogen in oxidation and that of transferable one in coking according to previous method.
