中文摘要：

超临界流体与膜分离的耦合技术的研究已经取得了很大的进展,其应用前景已经得到越来越多的关注,但仍然存在很多不足。其中超临界流体在多孔膜中的渗透扩散机理还不明确,理论计算模型较少。对超临界流体在多孔膜中的渗透扩散机理的实验研究现状进行阐述,并对采用分子模拟和计算流体力学的计算机理论模拟进行分析讨论。最后,指出今后应着力发展的方向。

英文摘要：

The research of coupling supercritical fluid technology with membrane separation process has gotten great progress.It has a good prospect of application and has drawn more and more attention.But there still exist many problems,which include that the supercritical fluid infiltration diffusion mechanism in porous membrane is not clear and theoretical calculation model is less.In this paper,recent research progress in supercritical fluid infiltration diffusion mechanism in porous membrane was expounded,and the computer simulation by using molecular simulation and computational fluid dynamics was analyzed and discussed.In the end,the development direction in the future was put forward.
