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

摘要节型醇脱制备醇的方法主要有4种：共沸精馏法、萃取精馏法、吸附法和分离法。

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.

多孔陶瓷在毛细管冷凝传质机理的作用下有效地分离吸附性气体。而毛细管冷凝分离传质机理的研究还很不充分,目前,文献报道仅局限于纯组分气体的传质模型研究。
