摘要
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。
Residues of two Middle East crudes (Saudi Arabian light crude and Oman crude) were separated by Supercritical Fluid Extraction and Fractionation. Each residue and their sub fractions were characterized by the average molecular weight, H/C ratio, density, refractive index, carbon residue, viscosity,sulfur, nickel and vanadium contents. Saturates, aromatics, resin and asphaltenes contents and structural parameters were determined. Compared with properties of subfractions of Daqing and Liaohe residues.some important information were obtained for the processing of residues of Saudi Arabian light crude and Oman crude.
