摘要:采用Monte-Carlo模拟方法,建立了表征重油组成的等过分子系综法,提出了重油分子构造规则和约束及有关计算机算法。Alberta重油的模拟结果和实验数据比较表明,其系统计结构基团浓度,密度,沸点,环、桥和侧链分布,饱和烃含量均与实测一致,从而为利用纯化合物物化性质研究复杂的重油建立起桥梁。
A hcavy oil distillate was modelled by building and ensemble of representativemolecules,using Monte-Carlo program. Each molecule was constructed using structural ele-ments which have been identified in heavy oil mixtures·The ensemble of the constructedmolecules agrees with the actual boiling point distribution,the concentrations of structuralgroups,the density,the ring distrubution,the bridge and side chain distribution,and thecontent of saturates. The correlations of properties between pure compounds and complexmixtures of heavy oils could be buiIt by the proposed method.
