摘要
利用摩尔折射度的基团加和性,推导出烃类及其混合物的总热值和净热值与其折光指数n、密度d、平均分子量M间的关联式。用大庆原油的十八个馏分检验了它的准确性,并确定了关联式中的参数。利用此关联式可方便地由烃类混合物或纯烃类化合物的n、d、M数据较精确地求得相应的热值或△H_c^0。
A new corrolation between the heat of combustion (gross or net) of hydrocarbons or their mixtures and their refraction index n, density d, and average molecular weight M has been established from the group addition property of molecular refraction index. This model has been verified experimentally and the parameters in this model have been obtained from the data of eighteen fractions of Daqing crude oil. This model canbe conveniently used to estimate the heat of combustion of pure hydrocarbons or their mixture from their n, d and M values.
