Abstract

According to modern coal chemical structure theory, the active chemical structure categories in coal spontaneous combustion process were summed up, which show that the coal spontaneous combustion characteristic structures are dynamic, such as methyl, methylene, hydroxyl, carbonyl and others in coal bridge bonds and side chains. The amount and activity of these structures play an important role in coal low temperature oxidation stage. Based on this, the article analyzed the effect of ionic liquids to coal spontaneous combustion characteristic structures, which indicates that the structure amount of coal affected by ionic liquids decreases obviously compared with raw coal.
