Applications of Carbon-based Membranes for Separation Purposes

Applications of Carbon-based Membranes for Separation Purposes 

As stated in Chap. 6, most of separation experiments using CMSMs have been performed for gas separatioa Many examples have already given throughout the foregoing chapters. In contrast, only few papers have been published for ultrafiltra-tion(UF)[l,2]. 

The most important large application of carbon membrane seems in the production of low cost and high purity nitrogen from air. Other examples are separation of hydrogen from gasification gas, purification of methane [3]. In addition, it is used to recover a valuable chemical (H ) from a waste gas stream without further compression of the feed gas while rejecting a substantial portion of the hydrocarbons [4].
