| 摘 要： | 通过对石油馏分一次加工油和二次加工油分子量的考察,优选了分子量和沸点(T)、相对密度,特性因素(UOPK)的关联式。对大量纯化合物的T和碳原子数的回归,得到了T、碳数和UOPK的函数关联式。将石油馏分按碳数大小分成若干个虚拟组分,对每个碳数虚拟组分赋以分子量、UOPK、硫、氮含量、摩尔流率、碳原子数流率等数值,即可在加氢等工艺预测性动力学模型建立中,预测产品性质。

| Abstract: | Good correlated equations about molecular weight has been selected with the experimental data for petroleum fractions from distillation and other processing. Related equations for boiling points, carbon numbers and characteristic factor K were regressed from the informations of a large number of pure hydrocarbon compounds. Petroleum fractions were considered to be broken down into carbon number pseudocomponents. In this paper, they were further characterized by determining their molecular weight, characterized factor K, sulfur and nitrogen contents and mole and carbon number flow rate in addition to the aromatic carbon, naphthenic carbon and paraffinic carbon fractions. These charaterization steps were presented and compared. These rusults can be applied for predicating properties of various products in kinetic modelling of hydrogenation and other processes. |
