| 摘 要： | 进行了热碱水抽提内蒙古油砂中沥青的实验研究。结果表明，最佳抽提条件为：碱液浓度0．3％，抽提温度90℃，碱液／油砂质量比1．5～2．0，搅拌速度75～100r／min，抽提时间20min。在抽提得到的粗沥青中加入质量分数为20％的石油醚（馏程60—90℃），于45℃下进行了进一步的脱砂处理。结果表明，砂粒与沥青基本分离，所得沥青中沥青质的质量分数达43．40％。

| Abstract: | The experiment of extracting bitumen from Inner Mongolia oil sand by hot alkaline solution was investigated. The results showed that the optimal conditions of extraction were：concentration of alkaline solution 0.3% , extraction temperature 90℃, the mass ratio of alkaline solution to oil sand 1.5 - 2.0, stir speed 75 - 100 r/min and reaction time 20 min. The obtained bitumen was further detached with pc-troleum ether （boiling range 60 -90℃ ） of mass fraction of 20% at 45℃. The results showed that the bitumen was basically and the mass fraction of seperated from the sand, asphahine in the bitumen could reached 43.40%. |
