运用超临界流体萃取分馏技术，对两种中东原油（沙特轻质原油与阿曼原油）的减压渣油进行分离，测定与分析了窄馏分的折光指数、密度、粘度、残炭、平均相对分子质量、元素分析（C、H、S）、金属含量（Ni，V）、族组成（饱和烃、芳香烃和胶质含量）及结构组成。并与大庆、辽河原油的减压渣油分离结果进行了对比，为沙特轻质原油及阿曼原油的减压渣油的合理加工提供了重要的基础数据。
Using vacuum supercritical fluid fractionation technology, vacuum distillation residue of two Middle East crude oil (Saudi Arabian crude oil and Oman crude oil) was separated and measured. The refractive index, density, viscosity, carbon residue, mean relative molecular weight Quality, elemental analysis (C, H, S), metal content (Ni, V), family composition (saturated hydrocarbons, aromatic hydrocarbons and gum content) and structural composition. Compared with the results of vacuum residue separation in Daqing and Liaohe crude oil, the results provide important basic data for the rational processing of vacuum residue in Saudi Arabian crude oil and Oman crude oil.
