| 6. | The resin contents are about the same for fractions of two feeds and increase gradually 两种油浆的胶质含量基本相同,且呈缓慢递增趋势。 |
| 7. | The aromatic factors of liaohe decanted oil are much higher than those of daqing decanted oil at the same cumulative yield 在相同累积收率时,辽河油浆窄馏分的芳碳率远大于大庆油浆窄馏分。 |
| 8. | Supercritical fluid extraction and fractionation ( sfef ) are used to separate daqing and liaohe decanted oils into a number of narrow fractions 摘要以大庆和辽河油浆为研究对象,采用超临界流体萃取分馏技术将其切割成窄馏分,分析了油浆窄馏分的性质及组成随收率变化的规律。 |
| 9. | As the cumulative yield reaches 70 % for daqing decanted oil or 25 % for liaohe feed , the content of aromatics exceeds that of saturates and goes up rapidly while the saturates drop down by the same level 大庆、辽河油浆分别在累积萃取收率达70 %和25 %后,窄馏分中的芳香分含量超过饱和分且迅速增加,而饱和分含量相应下降。 |
| 10. | The density , viscosity , refractive index , molecular weight and sulfur amount of the fractions are on the increase with the increasing cumulative yield , while their molecular weight exhibits a narrow distribution from 300 to 400 研究表明,随累积萃取收率的增加,大庆和辽河油浆窄馏分的密度、粘度、折光率、硫含量及芳碳率呈增大趋势,油浆窄馏分的相对分子质量分布较窄( 300 ~ 400 ) 。 |
