Abstract The capture, storage, and utilization of small gases by economically
viable recyclable microporous adsorbents is an ever-expanding field of research
toward industrially relevant separations, as well as toward pollution remediation
and catalysis. The use of thermochemically stable zeolitic adsorbents has the potential to fill these markets, as they are already widely used industrially, compared to
other crystalline adsorbents such as metal organic frameworks and activated carbons.
In this chapter, we discuss the use of small-pore zeolites in the adsorption and
separation of small gases (e.g., CO 2 , C 2 H 4 , C 3 H 6 , NO x , etc.), based on how their
