重质油的氢碳原子比与核磁共振氢谱之间关系的研究

Study on Relationship between Atomic Ratio of Hydrogen to Carbon and 1HNMR of Heavy Oils

对炼油厂的催化油浆、重催油浆和催化重焦蜡进行元素和核磁共振分析 ,研究其氢碳原子比与核磁共振氢谱之间的关系。结果表明 ,核磁共振氢谱中 0 5～ 2 ppm、1～ 2 ppm、2～ 4ppm、6～ 9ppm区间的氢分率与重质油的氢碳原子比存在着较好的线性关系 ,其相关系数≥ 0 .96 ,氢碳原子比的计算值与实测值的平均误差≤ 3.6 0 %。

The relationship between atomic ratio of hydrogen to carbon and 1HNMR spectra of heavy oils has been investigated.A linear relationship exists between the atomic ratio of hydrogen to carbon of Catalytic Oil Slurry,Heavy Catalytic Oil Slurry,Catalytic Heavy Tar Waxy Oil and the percent of 0.5-2 ppm,1-2 ppm,2-4 ppm,6-9 ppm regional hydrogen in 1HNMR spectra.The coefficient of relevance is greater than or equal to 0.96,the average error is less than or equal to 3.60%.
