Incorporation of facilitating agents is one of the promising strategies being researched in recent years to cross the Robeson bounds for gas separations using polymeric membranes. The ways in which such inclusions modify the performance of membranes are not always clear. Here, we study the performance of two glassy membranes, Polyfurfuryl alcohol and Polysulfone, in O2/N2 and CO2/N2 separations, with Cobalt phthalocyanine in insoluble and solubilized forms as the facilitating agent. The results show that in general, three effects are important: (1) a barrier effect, (2) a facilitation effect, and (3) morphological effects on the polymer matrix due to an incompatibility between the particles and the polymer. These results provide some insight into the action of facilitating agents in soluble and insoluble form, when used as membrane additives. © 2017 American Institute of Chemical Engineers AIChE J, 2017

关于促进剂通过玻璃态聚合物膜对气体渗透的作用的一些机械学见解

促进剂的掺入是近年来研究的突破Robeson界线以使用聚合物膜进行气体分离的一项有前途的策略。这种内含物改变膜性能的方式并不总是很清楚。在这里,我们以不溶和增溶形式的酞菁钴为促进剂,研究了O 2 / N 2和CO 2 / N 2分离中的两种玻璃状膜(糠醇和聚砜)的性能。结果表明,总体而言,三个作用很重要:(1)屏障作用;(2)促进作用;(3)由于颗粒和聚合物之间的不相容性,对聚合物基质的形态学影响。当用作膜添加剂时,这些结果为可溶和不可溶形式的促进剂的作用提供了一些见识。©2017美国化学工程师学会AIChE J,2017
