Zeolites are microporous, aluminosilicate minerals commonly used as commercial adsorbents and catalysts. The term zeolite was originally coined in 1756 by Swedish mineralogist Axel Fredrik Cronstedt, who observed that rapidly heating a material, believed to have been stilbite, produced large amounts of steam from water that had been adsorbed by the material.

For natural zeolites, a large pore diameter (12 Å) favors ethylene (kinetic diameter 3.9 Å) to pass through zeolite pore openings and be absorbed within the zeolite framework (Erdogan et al., 2008; Szwedzinska, 2015). There are two theories to explain this phenomenon.
