采用￣１Ｈ－ＮＭＲ和￣（１３）Ｃ－ＮＭＲ谱，结合元素分析等数据，估计了重油和沥青中各种类型芳香碳，建立了较完整的表征方法．在模型混合物核磁共振谱基础上，指定￣（１３）Ｃ－ＮＭＲ谱中１２９．５～１５０（ｐｐｍ）＋１２３．５～１２６（ｐｐｍ）／３谱带作为非质子芳碳．模型混合物校核表明，用本方法估计的桥头芳碳和环烷并芳碳与实际值吻合良好；估计的四种Ａｌｂｅｒｔａ沥青质样品的各种类型芳碳．其结果与Ｓｔｒａｕｓｚ化学分析的结果一致． H -1 NMR and 13 C-NMR spectra were used in combination with the data of elemental analysis to estimate various types of aromatic carbon in heavy oil and bitumen, and a more complete characterization method was established. Based on the NMR spectrum of the model mixture, 129.5-150 ppm and 123.5-126 ppm / 3 of the 13 C-NMR spectrum were designated as aprotic aromatic carbon. Verification of the model mixture showed that the bridgehead aromatic carbons and naphthenic aromatic carbons estimated using this method agree well with the actual values; various types of aromatic carbons for the four Alberta asphaltene samples are estimated. The results are consistent with the results of Strausz chemical analysis.
