臺灣博碩士論文加值系統

本研究以戊烷、己烷和環己烷的混合物做為汽油的替代物，希望以此來探討水在酒精汽油中的溶解度，分別在293.15 K、303.15 K及308.15 K三個溫度下進行液液平衡實驗。本實驗在每一個溫度下進行了三組三成份的液液平衡實驗，包括：乙醇-水-戊烷、乙醇-水-己烷及乙醇-水-環己烷；三組四成份的液液平衡實驗，包括：乙醇-水-戊烷-己烷、乙醇-水-戊烷-環己烷及乙醇-水-己烷-環己烷；一組五成份的液液平衡實驗：乙醇-水-戊烷-己烷-環己烷。用UNIQUAC液相模式來回歸每個系統的兩成份參數，最後在五成份系統的回歸中，有不錯的擬合結果。

In this study, the limit of water dissolved in gasoline was studied. The mixture of pentane, hexane, and cyclohexane were considered to represent the gasoline. In order to investigate the behavior of this tolerance, the liquid-liquid equilibria of three ternary systems: ethanol- water-pentane, ethanol-water-hexane, and ethanol-water- cyclohexane, of three quaternary systems: ethanol-water-pentane-hexane, ethanol-water- pentane-cyclohexane, and ethanol-water-hexane- cyclohexane, and of one quinary system: ethanol-water-pentane-hexane- cyclohexane, were studied. The experiments were conducted at 293.15, 303.15, and 308.15 K. The experimental data were correlated with the UNIQUAC activity model and the interaction parameters of all binary pairs among these compounds were determined. As the results of study, a good correlation was obtained for quinary system with the binary interaction parameters determined in this study.
