以克拉玛依油砂为实验对象，考察石油醚、环己烷、正戊烷、正庚烷、甲苯、CS2及复合溶剂 EOSA 萃取分离油砂沥青的效果，确定 EOSA 为最佳萃取溶剂。研究了温度、溶剂用量、时间对 EOSA 萃取分离油砂沥青收率的影响。结果表明，在萃取温度30℃、剂砂比2 mL/ g 条件下萃取30 min，油砂沥青的收率可达95％以上。再生实验结果表明，在60~80℃条件下，溶剂回收率超过99％。该工艺具有无水参与、零排放、低能耗、高收率等优点。

Take Karamay oil sands as a experimental subject,investigate the extraction and separation re-sult of oil sands bitumen with various solvents including petroleum ether,cyclohexane,n-pentane,n-hep-tane,toluene,carbon disulfide and composite solvents EOSA. EOSA is selected as the optimal solvent. The effect of extraction temperature,amount of solvent and the extraction time to the yield of oil sands bitumen was investigated. The result shows that under the conditions of extraction temperature of 30 ℃ ,solvent to oil sands ratio of 2 mL/ g,extraction time of 30 min,the yield of oil sands bitumen can reach above 95% . The regeneration experimental result shows,under the conditions of 60 ~ 80 ℃,more than 99% of the sol-vent can be recyclable. This process has various advantages including anhydrius participation,zero emis-sions,low energy consumption,high yield and so on.
