Thermal decomposition behavior of coals were measured by high temperature infrared spectrophotometer (IR) system. It is important to know the thermal decomposition process of coals in order to understand their chemical properties during coking reaction. The coal samples were heated from 50℃ up to 600℃ in a N_2 ambience, and IR spectra were measured in every 10℃. Five coals were analyzed by this system, the changes of IR spectra as sample heating were well obtained. Especially, high temperature region over 400℃, drastic changes of IR spectra were obtaind. The high temperature IR system is useful for analysis of thermal decomposition behavior of coals.
