Modification of Zeolite Membranes for H2

Introduction Zeolite membranes have the potential to efficiently separate gas mixtures because they have pores in the appropriate molecular size range and they have a narrow size distribution. The high thermal, chemical, and mechanical stabilities of zeolite membranes make them ideal for use in high-temperature applications such as H2 separation from coal gasification products.

Membrane gas separation - Wikipedia

While polymeric membranes are economical and technologically useful, they are bounded by their performance, known as the Robeson limit (permeability must be sacrificed for selectivity and vice versa). This limit affects polymeric membrane use for CO 2 separation from flue gas streams, since mass transport becomes limiting and CO 2 separation becomes very expensive due to low permeabilities.
