Energy-saving ethanol dehydration techniques to produce dehydrated alcohol mainly included four measures as azeotropy distillation, extraction distillation, absorptive process and membrane separation.

摘要节能型乙醇脱水制备无水乙醇的方法主要有4种：馏法、萃取馏法、吸附法和膜分离法。

Adsorbable gases can be separated by porous ceramic membranes under the capillary condensation mechanism of membrane separation, on which prior study was only limited to pure components.

多孔陶瓷膜在毛细管冷凝传质机理的用下能够有效地分离吸附性气体。而毛细管冷凝膜分离传质机理的研究还分,目前,文献报道仅局限于纯组分气体的传质模型研究。
