摘要
从室温至300℃范围,每隔50℃分别对空气中大明煤进行2h氧化,运用13C固体核磁共振技术,分析大明煤及其氧化产物的分子结构,用分峰拟合方法分析煤分子中芳族碳和脂族碳的变化趋势,得到大明煤低温氧化规律．
Daming coal speimens were oxidized for 2 hours at an interval of every 50℃ from ambient temperature to 300% in the atmosphere. The chemical structure of the original coal and the residue were studied by solid state ^13C nuclear magnetic resonance （NMR）. The tendency of the aromatic and aliphatic carbons of the coal molecular was analyzed by peak fitting software, arriving at the rule of low-temperature oxidation process of coal.
