13c固体核磁共振分析煤中含氧官能团的研究
, PP. 1422-1426
Keywords: 煤,含氧官能团,13c-cp/masnmr,非活性醚键
Abstract:
？采用13c交叉极化/魔角旋转-核磁共振（13ccp/masnmr）技术对四种煤进行分析，结合化学分析方法，考察了含氧官能团的分布规律，尤其是非活性醚键的含量。结果表明，13ccp/masnmr方法可以定量分析煤中部分含氧官能团，四种煤中羧基和羰基的含量分别为0.00~1.41和0.45~1.91mol/kg；13ccp/masnmr与化学分析方法结合，可以定量解析煤中非活性醚键的含量，四种煤的醚键含量值为5.33~10.54mol/kg，而活性醚键含量仅为0.04~0.13mol/kg，煤中醚键的赋存状态以非活性醚键为主。
