摘要
本文利用高分辨~１ＨＮＭＲ和^（１３）ＣＮＭＲ对峰峰肥煤热解加氢产物的八个液体样品进行了研究。得到了各个馏分的氢、碳原子分布。结合元素分析、分子量测定等数据，计算了各馏分的平均结构参数，获得了峰峰肥煤的结构特征。除Ｆ＿（１１）馏分为各种烷烃组分外，其它馏分的芳香度均在０．２４～０．８８之间，其中Ｆ＿（１２）的最大，为０．８８，Ｆ＿（１４）馏分的ｆ＿ａ最小，为０．２４。各馏分的平均分子中所含的芳环数目从３到８不等，其中Ｆ＿（２４）平均分子中所含芳环数最多，为８个。
Several fractions of Feng Feng fat coal-derived liquid were investigated by high resolution ￣1HNMR and ￣(13)CNMR. The distribution of hydrogen and carbon was obtained. Combined with elemental analysis and VPO average molecular weight measurement,a series of structural parameters were calculated, such as aromaticity(fa), condensation index, aromatic rings per average molecule etc., The aromaticities of the fractions were between 0.24 and 0.88 except offor F_(11) fraction. The fa value of F_(12) fraction was the largest,0.88; while the fa value of F_(14) was the smallest 0.24. The aromatic rings per average molecule of these fractions were from 3 to 8. F_(24) fraction had the largest number of aromatic rings,8. The structural model for each fraction was given, and the strtictural characteristic of Feng Feng fat coal was obtained.
