| 摘 要： | 使用恒温固定吸附床对乙醇蒸汽脱水的术薯粉吸附剂的气相选择吸附性能进行研究。乙醇原料液的浓度为75％～95％（质量百分数），使用干燥过的木薯粉作为吸4；什剂，分别测得吸附床不同位置处、不同表观速率、不同吸附剂粒度和不同温度时的乙醇蒸汽的透过曲线并进行了分析。通过木薯粉吸附最终可获得99．7％（质量百分数）的无水乙醇。

| Abstract: | The adsorption capability of cassava meal for gaseous phase selective adsorption for ethanol dehydration was investigated via a bench - test fixed - bed adsorber at constant temperature. Ethanol content ration in the feed was 75% -95% （mass） and dried cassava meal was used as adsorbent, and breakthrough curves were obtained and analyzed for different bed depths, superficial velocities , granularities of adsorbent and temperatures. A product of ethanol purity of 99.7 % （mass） could be obtained through the cassava adsorbent . |
