摘　　要：在对比大量样品和实验数据的基础上对煤直接液化油窄馏分样品的计算方法进行了研究和讨论,通过与冰点降低法分析结果相比,考察了NEDOL法计算煤直接液化油窄馏分样品分子量的准确性.结果表明,用NEDOL法计算四种煤直接液化油窄馏分样品的分子量时,47个样品的计算结果与冰点降低法测定结果十分接近,对神华油样品来说,两种方法的平均误差为-1.7;对胜利油样品来说,两种方法的平均误差为-1.3;对内蒙油样品来说,两种方法的平均误差为-3;对黑山油样品来说,两种方法的平均误差为-2.7.NEDOL法可直接用于计算液化油平均分子量.In order to meet the needs of the rapid industrialization tion project, the calculation method for molecular weights of direct coal of direct coal liquefacliquefaction oil narrow boiling range fractions were studied based on the comparison of a great deal of experimental solvent samples and their molecular weights. In comparison with the results of freezing point depress method, the precision for calculating the molecular weights of coal liquefaction oil by NEDOL method was investigated. For Shenhua oil, average error is --1.7 between results of NEDOL method and freezing point depress method. For Shengli oil, average error is --1.3. For Neimeng oil, average error is --3. For Heishan oil, average error is --2. 7. The calculation results by NEDOL method are close to that of freezing point depress method. NEDOL method can be used to calculate molecular weights of direct coal liquefaction oil narrow boiling range fractions.
