摘要(Abstract)：

分析了煤基油窄馏分样品的计算方法,通过与冰点降低法结果的对比,考察NEDOL法计算煤焦油及焦油加氢产物窄馏分样品分子量的准确性。结果表明:用NEDOL法计算两种煤焦油窄馏分样品的分子量时,煤焦油A、B窄硫分平均相对误差分别为-6.60%和-11.75%,31个样品的计算结果与测定结果相差较大,NEDOL法不适宜计算煤焦油窄馏分平均分子量;用NEDOL法计算两种焦油加氢产物窄馏分样品的分子量时,焦油加氢产物C、D的平均相对误差分别为-3.44%和-5.86%,41个样品的计算结果与测定结果较接近,NEDOL法可用于计算焦油加氢产物平均分子量。
Analyse the calculation of narrow boiling range fractions of coal-derived oil. Compared with the results of freezing point depress method,investigate the precision for calculating the molecular weights of coal tar and coal tar hydrogenation products by NEDOL method.The results show that,with NEDOL method,the average relative error for coal tar A and B is-6. 60 percent and-11. 75 percent.Through calculating thirty-one samples,find that there is a notable difference between calculation and measure results. So the NEDOL method is not suitable for the calculation of relative molecular weight of narrow boiling range fractions of coal-derived oil. For coal tar hydrogenation product C,the average relative error is-3. 44 percent. For coal tar hydrogenation product D,the average relative error is-5.86 percent. Through calculating forty-one samples,find that NEDOL method can be used to calculate molecular weights of coal tar hydrogenation product narrow boiling range fractions.
