摘要：
The thermal behavior of 4 coal samples was investigated using simultaneous thermogravimetry (TG/DTG) and differential thermal analysis (DTA) methods. Upon heating the coals in an inert atmosphere up to 800degreesC, 31.44-43.82% weight loss occurs. The 2 temperature regions of increased chemical reactivity are evident in the coal samples studied Two different models determined kinetic analysis of the samples, and the results are discussed.
