An Investigation into the Thermal Behavior of Coals

Abstract

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 800 ° C, 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.
