| 摘 要： | 采用超临界流体萃取分馏技术，将减压渣油分离成6个窄馏分和1个萃余残渣，对窄馏分的组成分布和结构进行了研究，为减压渣油的的合理加工提供重要基础数据。结果表明，随着窄馏分收率的增加，饱和分质量分数减小，胶质质量分数增大，芳香分质量分数先增大，达到最大值，再减小，各窄馏分中基本不合沥青质，残炭值、及金属元素含量逐渐增加，金属在最后几个窄馏分和残渣中有富集现象。用改进的Brown—Ladner法计算了各个窄馏分和原料的结构参数。

| Abstract: | The vacuum residuum was separated into 6 narrow fractions and an end-cut by supercritical fluid extraction and fractionation （SFEF） technology. The group composition distribution and structure of narrow fractions were investigated, provided important basic data for properly using vacuum residue. The results indicate that as the yield of narrow fraction increased, the content of saturates decreased and that of resins increased, aromatics content increased begin, reaching the maximum, then decreased. There was little asphaltene in every narrow fraction, the content of residual carbon increased, as well as metal content. The average structural parameters of narrow fractions and vacuum residuum were calculated with modified Brown-Ladner method. |
