摘　　要：Mass transfer enhancement of gas absorption by adding a dispersed organic phase has been studied in this work. Various dispersed organic phases （heptanol, octanol, isoamyl alcohol, heptane, octane, and isooctane） were tested respectively in the experiment. According to the theoretical model and experimental data, the overall volumetric mass transfer coefficient and enhancement factor were obtained under different dispersed organic phase volume fraction and stirring speed. The experimental results indicate that gas-liquid mass transfer is enhanced at different level by adding a dispersed organic phase. The best performance of enhancement were achieved with the dispersed organic phase volumetric fraction of 5% and under an intermediate stirring speed of 670 r·min^-1. Among the organic phases tested in the experiment, alcohols show better performance, which gave 20% higher enhance-ment of overall volumetric mass transfer coefficient than adding alkanes.由增加一个驱散的器官的阶段的煤气的吸收的集体转移改进在这个工作被学习了。各种各样的驱散的器官的阶段(heptanol， octanol， isoamyl 白酒， heptane，辛烷，和异辛烷) 在实验分别地被测试。根据理论模型和试验性的数据的意见，全面容量的集体转移系数和改进因素在不同驱散的器官的阶段卷部分和激动人心的速度下面被获得。试验性的结果显示煤气液体的集体转移被增加一个驱散的器官的阶段在不同水平提高。改进的最好的表演与驱散的器官的阶段被完成 5% 并且在 670 r 慭整楲污 ? 硥楨楢? 硥散汬湥 ?敭档湡捩污瀠潲数瑲敩 s
