摘　　要： 研究木薯吸附剂生产无水乙醇的工艺。对木薯吸附剂进行了SEM表征,应用BET二参数理论计算木薯吸附剂的比表面积,对木薯吸附剂的吸附等温线进行Sircar模型预测和分析。采用固定床吸附工艺,从生产能力、破点时间、操作条件的影响等对木薯吸附剂的吸附性能进行了研究。结果表明,木薯吸附剂属于BrunauerII型吸附等温线,且比表面积大,吸附能力强。采用木薯吸附剂固定床吸附法生产无水乙醇的工艺是可行的。 The production of anhydrous ethanol by use of cassava absorbent was studied. The characterization of cassava absorbent was measured by SEM, the specific surface area of cassava absorbent was calculated based on BET two parameter theory and the absorption isotherm of cassava absorbent was analysed with Sircar model prediction model. Then the technique of fixed-bed absorption was applied, and the absorption performance of cassava absorbent was investigated from the aspects of production capacity, break time and the impact of different operating conditions etc.. The research results indicated that the absorption isotherm of cassava absorbent belongs to BrunauerlI type, the specific surface area of cassava absorbent is large, and the absorption capability of cassava absorbent is strong. It proved that the use of fixed-bed absorption technique by cassava absorbent to produce anhydrous alcohol is feasible in practice.
