【摘要】 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，可供进一步研究更多还原

【Abstract】 An analysis for the heavy oil of Nanjing Refinery by 1 H-NMR spectra and column chromatography have been carried out. The results show that there are differences among the Hydrogen adding Tail Oil, Catalytic Oil Slurry, Heavy Catalytic Oil Slurry and Catalytic Heavy Tar Waxy Oil. The each heavy oil havs respective characteristics of 1 H-NMR spectrum. The Hydrogen adding Tail Oil contains the paraffin hydrocarbons and alicyclic hydrocarbons more then 96.8 percent, and contains the aromatic hydrogen less then one percent. The Catalytic Oil Slurry and Heavy Catalytic Oil Slurry contain the aromatic hydrocarbons between 42～66 percent, and contain the aromatic hydrogen between 15～31 percent. The Catalytic Heavy Tar Waxy Oil contains the aromatic hydrocarbons between 13～23 percent, and contain the aromatic hydrogen between 3～6 percent. That can distinguish the classification of the heavy oils.更多还原
