摘要
进行了超临界CO_2萃取分离乙醇与水混合物的实验研究。考察了各种操作条件和填料对萃取的影响,发现填料对改善萃取过程有明显的效果。探索了添加剂在超临界萃取中的作用,获得具有前景的结果。
The experimental study of seperation of ethanol-water mixture with supercritical carbon dioxide was carried out. The influence of various operation conditions and with or without packings in extractor was examined. It was shown that packings improved the efficiency of extraction evidently. At the same time,the effect of additive agent in supercritical fluid extraction was also investigated.
