Effect of soaking on coal oxidation activation energy and thermal effect

In order to study the effect of soaking on coal spontaneous combustion,the coal samples with different ranks were selected,and the FT-IR and thermos-gravimetric experiments were carried out on the same moisture content of raw coal and soaked coal.Compared the Infrared Spectra,it is found that the active groups in the soaked coal increase and the oxidation activity is higher than that of raw coal.Based on the TG curves and the theory of ignition...
