膜分离

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

摘要节能脱水制备无水方法主要有4种：共沸精馏法、萃取精馏法、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质机理用下能够有效地分离吸附性气。而毛细管冷凝膜分离质机理研究还很不充分,目前,文献报道仅局限于纯组分气质模研究。
