What are the Different Types of Molecular Sieves?

By Delta Adsorbents

Molecular Sieves are available in:

3A Molecular Sieve

3A means that the pore size measures as 3 angstrom.  Anything larger than 3 angstrom won’t be able to be adsorbed. The order of adsorption rate is helium, neon, nitrogen and water.

3A EDG Molecular Sieve

This Molecular Sieve was made with drying fuel grade ethanol in mind.  Ethanol can only be dried to the azeotropic point of 95.6% purity by traditional distillation.  This is the method of drying that is picked by fuel ethanol producers.

4A Molecular Sieve

4A means that the pore size measures as 4 angstrom.  Anything larger than 4 angstrom won’t be able to be adsorbed. The order of rate of adsorption is argon, krypton, xenon, ammonia, carbon monoxide, C2H4, C2H2, CH3OH, C2H5OH, CH3CN2, CS2, CH3CL, CH3Br, and carbon dioxide.

4A is similar to 4A Molecular Sieve however it is injected with an inorganic metal salt moisture indicator. The important thing is that it is visibly noticeable to determine when the mole sieve attains saturation.  The molecular sieve beads turn blue when they becoming active.  The beads are colored beige when they are saturated.

5A Molecular Sieve

5A means that the pore size measures as 5 angstrom.  Anything larger than 5 angstrom won’t be able to be adsorbed. The sequence rate of adsorption is C3-C14, C2H5CL, C2H5Br, CH3L, C2H5NH2, CH2CL2CH2Br2, CHF2CL, CHF3, CF4, (CH3)NH2, B2H6CF2CL2, CHFCL2, and CF3CL.

13X Molecular Sieve

This Mole Sieve is considerably larger any of the other A type openings.   Its pour size is 10A.  This desiccant is used mainly for modifications of gases and liquid because it offers corresponding absorption for bi-molecule and tri-molecule.  The sequence rate of adsorption is SF6, CHCL3, CHBr3, CHI3, N-C3F8, CCL4, N-C4F10, N-C7H16, CBr4, C6H6, B5H10, (CH3)3N, C(CH4)4, (C2H5)3N, C(CH3)C3CL, C(CH3)3Br, and C(CH3)3CH.

Molecular Sieve Desiccant Packs

Molecular sieve is the effective option for eliminating water from gases and liquids. Usually products like alumina desiccants and silica gel have been used for such purposes, molecular sieve desiccants can give cleaner outcomes.  When it comes to Mole sieve construction is the key. The sieves have tiny and uniform pores, which makes them ideal adsorbents.
