The pore size of 13x molecular sieve(APG) is about 10 A. It can adsorb any molecular smaller than 10 A mainly used as catalyst carrier, coadsorbtion of CO2 and H2O and H2S as desiccant for medical and air compressor systems and can also be adjusted to fit other various applications.
Technical Bulletin
MOLECULAR SIEVE 13X (10A)
Molecular sieves are synthetic zeolites (complex alumino-silicates of sodium, potassium or calcium) of various pore sizes, When the water of hydration is driven off which result in an empty network called pores / cavities. Due to their unique crystal structure the cavaities and pores are precisely uniform in size which selectively adsorb molecules of a specific size. This strong adsorptive force allows molecular sieves to remove many gas or liquid impurities to ppm or less levels. Our Molecular sieve exhibits high resistance to attrition and physical damage during service.
The sodium form of 13X(10A) represents the basic structure of the type X family, with an effective pore opening of -7.2 angstrom which can be stretchable up to -10 angstrom diameter range.

Major Applications: Type 13X is uesed commercially for general gas drying, air plant feed purification (simultaneous removal of H2O and CO2) and liquid hydrocarban and natural gas sweetening (H2S and mercapstan removal). A;; molecules which can not be adsorbed on type 13X. In addition, type 13X can adsorb molecules of larger critical diameters, such as aromatics and branched-chain hydrocarbons.
