| 摘 要： | 用汽相循环法,在夹带剂乙二醇或丙三醇的存在下,测定了313.2K,10MPa下CO_2-C_2H_5OH-H_2O-夹带剂的四元相平衡数据,对试验数据进行了处理分析。结果表明:10mol％的夹带剂加入原料中,可提高二氧化碳对乙醇-水的分离选择性,但是还不能打破乙醇-水的常压恒沸点。 |

| Abstract: | Vapor- Liquid equilibria for quaternary system of CO_2- ethanol - water - entrainer were determined at 313.2K and under 10MPa using a vapor circulation apparatus. The experiments were carried out for tWO kinds of entrainer: ethylene glycol and glycerol. It was found that the selectivity for separating ethanol-water with supercritical CO_2 could be raised by the addition of 10 mole % concentration of entrainer in feed, and yet unable to exceed the azeotropic composition of ethanolwater under atmospheric conditions. |
| Keywords: | entrainer phase equilibrium carbon dioxide ethanol water |
