Experimental Study on Infrared Spectrum Characteristics of Coal in Low Temperature Oxidation
Coal spontaneous combustion is a complex procedure of physical and chemical changing,in which the macro characters is the reflection of micro changes of coal molecule structure in low temperature oxidation.In order to understand the essence of coal-oxygen composition,the Fourier transform infrared spectrum apparatus is used to test and analyze different kinds of coal samples in different oxidation temperature.According to main characteristic spectrum peaks,the activity of coal functional groups is studied.The difference and change of the type and quantity of functional groups in different kinds of coal sample in different temperature are analyzed.The relation between the macro structure change and spontaneous combustion property of coal in low temperature oxidation process is discussed.
