从核磁共振氢谱推导的重质油氢碳原子摩尔比计算式

Calculation Equation from Mole Ratio of Hydrogen Atom to Carbon Atom Based on 1H NMR of Heavy Oils

通过对炼油厂的催化油浆、重催油浆和催化重焦蜡油核磁共振氢谱中质子归属和重质油结构的假设 ,推导出计算这3种重质油的氢碳原子摩尔比计算式 ;结果表明 ,氢碳原子摩尔比的计算值与实测值非常接近 ,平均误差仅为3.1%。

Calculation equations for mole ratio of hydrogen atom to carbon atom in catalytic oil slurry, heavy catalytic oil slurry and catalytic heavy tar waxy oil have been derived based on the assignment of their 1H NMR spectra and assuming structure of the heavy oils. The mole ratios of hydrogen to carbon in the three heavy oils calculated on the equations agree quite with those obtained by elemental analysis. The average errors are no more than 3.1%.
