Proximate Analyses

The drying experiments of three typical kinds of Inner Mongolia lignite were conducted on a self-designed apparatus. The proximate analyses and oxygen adsorbing capacities of all the samples were analyzed on an industrial analyzer and a coal spontaneous combustion tendency tester. The results show that the treated samples show no apparent changes in their properties compared to the original lignite and no pyrolysis or combustion phenomenon occurs in the drying process. It is also observed that the oxygen adsorbing capacity of the dewatered sample is lower than that of the original lignite. Especially the oxygen adsorbing capacity of the lignite sample undergoing high-temperature drying process decreases significantly. Considering the amount of adsorbed oxygen can reflect the spontaneous combustion tendency of coal to a certain extent, the spontaneous combustion tendency of the treated lignite decreases.
