Zeolite 13X

CAS 63231-69-6

Zeolite 13X separates gases by reversible adsorption, with framework chemistry and cations influencing how strongly different guests are retained. Its type designation is not a direct measurement of a thirteen-angstrom entrance, and visible pellet size is a separate property. Research on hydrogen, carbon dioxide, and methane has combined equilibrium measurements with breakthrough experiments to examine practical separation behavior. A bed can initially retain an impurity and later release it at the outlet as capacity is used. Water also competes for adsorption, so dry-gas results do not automatically describe a humid feed. Regeneration completes the picture: a useful adsorbent must release captured material as well as hold it. The complete repeated operating cycle matters more than a single maximum uptake measurement.
