１Ｈ－ ＮＭＲ 法结合经典柱层析法，对南京炼油厂加氢尾油、催化油浆、重催油浆和催化重焦蜡油进行了研究。实验结果表明，不同的重质油有不同的谱图特征，根据谱图中各部分氢的积分面积和特征，可以判断重质油的类别。加氢尾油中含９６ ．８ ％ 以上的饱和烃和环烷烃，芳香烃含量最少，其芳香氢含量小于１ ％ ；催化油浆和重催油浆中含芳香烃最多，达４２ ％ ～６６ ％ ，饱和烃和环烷烃含量最少，在２３ ％～４５ ％ 之间，其芳香氢含量在１５ ％ ～３１ ％ 之间，它们的核磁共振谱图相似，所以将它们归结为同一类；催化重焦蜡油中含６６ ％ ～７６ ％ 的饱和烃和环烷烃，含芳香烃１３ ％ ～２３ ％ ，其芳香氢含量在３ ％ ～６ ％ 之间。在１Ｈ－ ＮＭＲ 谱图中各部分氢的积分面积与重质油的族组成有着某些关系，可供进一步研究
1H-NMR combined with classical column chromatography, the Nanjing refinery hydrogenation tail oil, catalytic slurry, heavy oil slurry and catalytic heavy coke oil were studied. The experimental results show that different heavy oils have different spectral characteristics. According to the integral area and characteristics of hydrogen in each part of the spectrum, the classification of heavy oil can be judged. Hydrogenation tail oil contains 96. More than 8% of saturated hydrocarbons and naphthenes, aromatic hydrocarbon content of the least, the aromatic hydrogen content of less than 1%; catalytic slurry and heavy oil slurry containing aromatic hydrocarbons up to 42% to 66%, saturated hydrocarbons and naphthene content At least, between 23% and 45%, the aromatic hydrogen content is between 15% and 31%, their NMR spectra are similar, so they come down to the same class; catalytic heavy focus oil containing 66% 76% of saturated hydrocarbons and naphthenes, aromatic hydrocarbons containing 13% to 23%, the aromatic hydrogen content of 3% to 6%. The integral area of hydrogen in each part of the 1H-NMR spectrum has some relationship with the composition of the heavy oil and may be further studied
